In this work, the effect of PMMA in low density polyethylene/water hyacinth fibers composites were prepared and characterized in terms of tensile properties and FTIR characteristics. Water hyacinth fibers (WHF) were incorporated into the LDPE matrix with different fiber loading. LDPE/WHF and LDPE/WHFPMMAcomposites were prepared with Z-blade mixer at 180 °C with rotor speed of 50 rpm. The PMMA modified WHF increased the tensile strength and Young’s modulus while reduced the elongation at break of LDPE/WHFPMMAcomposites in comparison with LDPE/WHF composites. The absorption peak at 1736.28 cm-1indicated the presence of ester carbonyl group (C=O) in LDPE/WHFPMMAcomposites.

Water Hyacinth Fiber

In this work, the effect of PE-g-MAH as compatibilizer in polyethylene/ natural rubber/ water hyacinth fibers composites were prepared and characterized in terms of tensile properties, morphology properties, swelling behavior and FTIR characteristic. Water hyacinth fibers (WHF) was used as reinforced fiber in the composites incorporated into the LDPE/NR matrices with different fiber loading. LDPE/NR/WHF composites were prepared with Z-blade mixer at 180°C with rotor speed of 50 rpm for 10 minutes. The presence of PE-g-MAH increased the tensile strength and Young’s modulus while reduced the elongation at break of LDPE/NR/WHF composites. The molar sorption of the composites decreased as the fiber loading increased. SEM morphology showed a better fiber dispersion and fiber distribution indicated PE-g-MAH improved the interfaces between water hyacinth fiber and LDPE/NR matrices. The absorption peak at 1741.52cm-1indicated ester carbonyl group in LDPE/NR/WHFPE-g-MAHcomposites.

The effect of dynamic vulcanization and fiber loading on properties of low density polyethylene (LDPE)/natural rubber (NR)/water hyacinth fibers (WHF) were investigated. In this study, the vulcanized thermoplastics were obtained by in situ dynamic curing of LDPE/NR/WHF composites. The LDPE/NR/WHF composites with different fiber loading were prepared by using Brabender mixer at 180 °C with the rotor speed of 50 rpm. The results showed that dynamic vulcanized LDPE/NR/WHF composites gave a higher tensile strength, Young’s modulus, elongation at break but lower molar sorption than unvulcanized LDPE/NR/WHF composites. The SEM micrographs also displayed better fibers dispersion and the crosslink formation in dynamic vulcanized LDPE/NR/WHF composites indicated better interfacial bonding among fibers and matrix compared to unvulcanized LDPE/NR/WHF composites.

Linear low-density polyethylene (LLDPE)/soya spent powder blends with different blends ratio were prepared by using internal mixer. Soya spent powder was varied from 5 to 40 wt. The thermal degradability was assessed by subjecting the dumbbell sample to oven aging. Thermal aging was carried out for 5 weeks. The degradability was measured by the periodic change in tensile properties of the blend samples. The tensile strength and elongation at break of the blends reduced as increasing the aging time. The effect of degradation was obvious in higher soya spent powder blends.

The compatibilizer effect of ENR-50 on the tensile properties and morphology of linear low density polyethylene (LLDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ rice husk powder (RHP) composites has been studied. The RHP size utilize in this work is 150 – 300 μm. LLDPE/NBRr/RHP composites were prepared by melt mixing technique at 180 °C for 9 minutes at 50 rpm rotor speed using heated two roll mill. The series of composites investigated were 100/0/5, 80/20/5, 70/30/5, 60/40/5, 50/50/5, and 40/60/5. The composites were analysed by using tensile test and morphology examination. The result showed that the tensile strength of composite was decreased with the increasing of recycled acrylonitrile butadiene rubber (NBRr) content while elongation at break (Eb) were increased. However, the tensile strength and elongation at break result for composites with ENR-50 as compatibilizer showed higher values. The morphological finding supports the tensile properties which indicate better interaction between the RHP filler and LLDPE/NBRr matrix in the presence of ENR-50 compatibilizer.

The effects of benzyl urea into RHDPE/NR/CFF composites with different fibers loading were studied. The composites were prepared using BrabenderPlasticorder at 160 °C with rotor speed of 50rpm. The composites were characterized in respect of their tensile properties and morphology. The results indicated that RHDPE/NR/CFF with benzyl urea composites show higher values of tensile strength, Youngs modulus, but lower elongation at break than RHDPE/NR/CFF composites. RHDPE/NR/CFF with benzyl urea composites gave a better interfacial adhesion between the matrix and the fiber than RHDPE/NR/CFF composites as evidence using SEM.

This research focused on the utilization of kapok husk (KH) as filler in low linear density polyethylene (LLDPE). The effect of filler content on tensile properties and morphology of LLDPE/KH eco-composites were investigated. The eco-composites were prepared by using Brabender Plasticiser EC Plus at temperature 160 °C and rotor speed 50 rpm. The results indicated that the tensile strength and elongation at break decreased with KH content increased. However, the modulus of elasticity increased with increasing of KH content. The morphology study of eco-composites exhibit poor interfacial adhesion between KH and LLDPE.

Anti-fog films of low density polyethylene (LDPE) modified with micrometer diatomite were prepared by a process of blow molding. Through examination of antifogging property of the film added the anti-fog agents, the modification effectiveness of inorganic micrometer diatomite and the influence of different treating agents were studied with Fourier transform infrared spectrometer (FTIR), mechanical properties, and antifogging performances. The results indicate that the anti-fog property of the film can be improved by premixing inorganic micrometer diatomite with the anti-fog agents; the film modified by inorganic micrometer diatomite added surface treatment agent has obviously effectiveness anti-fog properties than that the films modified only by the anti-fog agents. Addition of polyacrylamide can make the anti-fog durability of the films modified by inorganic micrometer diatomite be further prolonged. It was observed that the tensile strength does not show any decrease, however, elongation at break show a massive decreased.

Objectives. This work aimed to develop technology to produce biodegradable hybrid composite (BHC) films based on low-density polyethylene (LDPE) 115030-070 and thermoplastic starches (TPS) of various origins (corn, pea, and rice), with distilled monoglycerides as the plasticizer. The properties of the produced BHC films were studied and the optimal native starch : glycerol : monoglycerides ratio is proposed.Methods. TPS and BHC films based on this material were produced from different types of native starches in laboratory extruders (Brabender and MashPlast, Russia), and the extruded melts were subjected to ultrasonic vibrations. The structure and appearance of the BHC films were studied using scanning electron microscopy and rheology. Their biodegradability was assessed by immersing them in biocompost for three months. To evaluate the mechanical performance of the BHC films produced with and without ultrasound, the changes in tensile stress and elongation at break were determined during the biodegradation process.Results. The BHC films had a homogeneous structure, except small agglomerates (non-melted starch grains), which did not reduce their quality. The films with monoglycerides had high tensile strength, which was comparable with low-density polyethylene. After removing samples of the BHC films from the biocompost, their tensile strength decreased by 20%, which shows their biodegradability.Conclusions. The produced biodegradable composite films and the technology used to produce them will be applicable for the packaging industry to reduce environmental impact.

Wollastonite is one type of inorganic filler. The effects of wollastonite loading on tensile properties of wollastonite (WS) filled high density polyethylene (HDPE)/Natural Rubber (NR) composites was studied. The HDPE/NR/WS composites were prepared by using Brabender EC Plus at a temperature of 180 °C with rotor speed of 50 rpm for 10 min. It was found that the increasing of wollastonite loading had decreased the tensile strength and elongation at break, whereas the Young’s modulus of the HDPE/NR/WS composites had increased with the increasing of wollastonite loading.
