The laponite-poly (L-lactide) composite films are prepared by the method of solution blending with polylactide (PLA) and laponite. The result shows that the homogeneous and smooth composite film is prepared with 1, 4-dioxane. Thermogravimetry analysis (TG) and tensile strength studies demonstrate that the thermal stability and tensile strength are improved with the laponite added. The scanning electron microscopy (SEM) measurement indicates that the pores of composite films get uniform and network structure is more and more compact with compared to pure PLA film. The present study reveals that the laponite as a complexing agent can improve the mechanical properties and thermal stability of PLA.

Abstract This article presents the potential use of tree waste materials such as the leaves (L), branches (B) and trunks (T) of Azadirachta excelsa (Sentang) tree in the production of wood polymer composite (WPC). The WPC was fabricated from high-density polyethylene (HDPE) as bonding matrix, maleic anhydride (MA) as coupling agent, and Sentang tree waste particles (L, B and T) as filler, prepared using twin-screw extruder followed by injection moulding machine. The effects of incorporating these types of Sentang tree waste particle (at 35% and 45% particles loading by weight) on the thermal stability of WPC were reported. The chemical compositions of L, B and T were also determined and their influences on the thermal stability of WPC were discussed. The thermal behaviour was determined by using thermogravimetric analysis (TGA), whereas the chemical analysis using Technical Association of the Pulp and Paper Industry (TAPPI) methods. The addition of these tree waste particles as filler has increased the thermal stability of WPC compared to virgin HDPE (without any particle incorporation). The highest mass loss was experienced by virgin HDPE. It was also observed that chemical compositions of the particles played vital role in influencing the thermal stability of WPC.

Polymer composite film containing expanded polystyrene wastes, poly (ethylene-co-vinyl acetate), epoxidized neem oil and cassava starch was prepared by solution casting technique. The composite film was characterized by FTIR, NMR, X-ray diffraction, and FESEM analysis. The thermal stability of the polymer composite film was studied by TGA and DSC. Melting point, glass transition temperature and cold-crystallization temperature of the composite films were found to decrease with increasing percentages of epoxidized neem oil plasticizer, which point towards the enhanced segmental mobility of the polymer chain. TGA results show that plasticization has enhanced the thermal stability of the polymer composite. The prepared films show improved percentage elongation with moderate tensile strength and Young’s modulus. Soil burial test was adopted to check the biodegradability. The lower values of water absorption indicate the water-resistant nature of the films. This green synthetic approach offers a simple means of up-cycling waste thermocol in a cost-effective manner which imparts partial biodegradability with potential for packaging film and eliminates the usage of toxic chemicals.

Thermal analysis was performed to evaluate the impact of the addition of oil shale ash (OSA) to high-density polyethylene (HDPE) polymer matrix using differential scanning calorimetry (DSC) and thermo-gravimetric analysis (TGA). Extrusion and press molding processes were used to compound the OSA-filled HDPE polymer composites containing 0, 5, 15 and 25 wt% OSA, for which the thermal properties and the characteristics of the composites were studied. Investigation of the thermal properties of the OSA-HDPE composite is necessary for selecting processing conditions and the appropriate application field. The DSC results demonstrated that OSA addition only marginally affected the glass transition temperature Tg of the composite formulations. The melting temperature Tm showed a decreasing trend with increased OSA fraction, while the crystallization temperature Tcryst showed an increasing trend. The heat of fusion ∆Hm, the heat of crystallization ∆Hcryst and the percentage of crystallinity decreased on the addition of OSA filler. The TGA results demonstrated that the thermal stability of the polymer composite matches that of the neat polymer behavior up to 350 °C after which the thermal stability of the filled polymer composite increases with increased filler content. Above 360 °C, the weight loss of the neat polymer as well as of the polymer composite is accelerated up to 480 °C where all tested samples become fully degraded.
