Hydrophilic behaviour of carrageenan macroalgae biopolymer, due to hydroxyl groups, has limited its applications, especially for packaging. In this study, macroalgae were reinforced with cellulose nanofibrils (CNFs) isolated from kenaf bast fibres. The macroalgae CNF film was after that treated with silane for hydrophobicity enhancement. The wettability and functional properties of unmodified macroalgae CNF films were compared with silane-modified macroalgae CNF films. Characterisation of the unmodified and modified biopolymers films was investigated. The atomic force microscope (AFM), SEM morphology, tensile properties, water contact angle, and thermal behaviour of the biofilms showed that the incorporation of Kenaf bast CNF remarkably increased the strength, moisture resistance, and thermal stability of the macroalgae biopolymer films. Moreover, the films’ modification using a silane coupling agent further enhanced the strength and thermal stability of the films apart from improved water-resistance of the biopolymer films compared to unmodified films. The morphology and AFM showed good interfacial interaction of the components of the biopolymer films. The modified biopolymer films exhibited significantly improved hydrophobic properties compared to the unmodified films due to the enhanced dispersion resulting from the silane treatment. The improved biopolymer films can potentially be utilised as packaging materials.

A uniform, monodispersed superfine cuprous oxide (Cu2O) sphere with a mean diameter of 850 nm has been synthesized by solution reduction. The study reported the synthesis and thermal properties of Cu2O/PP composites for the first time. The surface modification of the superfine Cu2O sphere was carried out by using a silane coupling agent KH-570. Fourier-transform infrared (FTIR) spectroscopy and the thermogravimetric analysis (TGA) curve revealed that the Cu2O had been successfully modified by silane coupling agent KH570. The scanning electron microscope (SEM) shows that the modified Cu2O can be uniformly dispersed in the polypropylene (PP) matrix, because through surface modification, there are some active functional groups on its surface, such as the ester group, which improves its compatibility with the PP matrix. The thermal stability of Cu2O/PP composites was improved by adding a small amount of Cu2O (1 wt % of PP). Therefore, based on the potential bacteriostasis of cuprous oxide, the low cost of PP and the results of this study, it is predicted that Cu2O/PP composites can be used in infant preparation (such as milk bottles) with low cost and good thermal stability in the near future.

Application Scope

To expand the application scope and increase the demand for non-crimp fabrics (NCFs) as a lightweight vehicle material, the delamination and thermal strain in NCF composites must be restricted. Accordingly, to simultaneously improve the interfacial bonding and thermal stability of the NCF composites, in this study the epoxy resin, in which SiO2 nanoparticles was modified by a silane coupling agent, were infused to the stacked NCFs and between the layers of NCFs through the vacuum-assisted resin infusion molding (VARIM) process.

Thermal Stability Of

The rice husk ash/natural rubber (RHA/NR) composites were prepared by latex blending process using the RHA modified with silane coupling agent. The structure and morphology of modified RHA were studied. The dispersing performance of modified RHA in the composites was evaluated from the structure and thermal properties. The results indicate that silane coupling agent KH-570 can react with the carboxyl of the RHA surface, leading to a significant decrease in carboxyl absorption intensity and the obvious improvement in the dispersion of RHA particles in rubber matrix. As the modified RHA having grafted onto NR molecular chains can increase the interface force between RHA and rubber matrix, the thermal stability of RHA/NR composites thus can be improved. The RHA/NR composite of highest thermal stability can be prepared with RHA load of 5% shows the best.

Water hyacinth is an aquatic weed which has potential of natural fiber as raw material of composites. The mechanical properties and the availability of water hyacinth in tropical country are a potential that could be developed as natural fiber in composite. In this experiment, surface of water hyacinth treated by silane coupling agent for adhering with epoxy resin. Dry water hyacinth can be obtained by cold pressed and hot pressed which the temperature are varied. The tensile strength of water hyacinth that hot pressed treatment at 110 oC, is 28.36 N/mm2. Silane coupling agent is used for surface treatment. The immersion time of Dry water hyacinth in silane coupling agent is varied from 5, 10, and 15 minutes. The Composite with 15 minutes of immersion time of water hyacinth has the highest bending strength (20.524 N/mm2). From SEM observations showed that the influence of the silane coupling agent is very significant.
