In this study, hexagonal boron nitride (h-BN) nanosheets and Bombyx mori silk fibroin (SF) proteins were combined and electrospun into BNSF nanofibers with different ratios. It was found that the surface morphology and crosslinking density of the nanofibers can be tuned through the mixing ratios. Fourier transform infrared spectroscopy study showed that pure SF electrospun fibers were dominated by random coils and they gradually became α-helical structures with increasing h-BN nanosheet content, which indicates that the structure of the nanofiber material is tunable. Thermal stability of electrospun BNSF nanofibers were largely improved by the good thermal stability of BN, and the strong interactions between BN and SF molecules were revealed by temperature modulated differential scanning calorimetry (TMDSC). With the addition of BN, the boundary water content also decreased, which may be due to the high hydrophobicity of BN. These results indicate that silk-based BN composite nanofibers can be potentially used in biomedical fields or green environmental research.

Palm kernel shells (PKS) filled recycled high density polyethylene (rHDPE) biocomposites were produced using melt mixing. The biocomposites were prepared on Brabender Plasticorder at temperature of 185 °C and rotor speed of 50 rpm by varying filler loading (0 to 40 phr). In this study, the effect of PKS loading on rheological properties and thermal stability of rHDPE/PKS were investigated. Rheological study of the biocomposites was carried out by means of capillary rheometer under temperature of 190 °C, 200 °C and 210 °C. Thermal properties of biocomposites were studied by using thermo gravimetric analysis (TGA). The rheological results showed that the flowability of the composite increased with increasing temperature. Meanwhile, the result of TGA showed that at higher PKS loading, rHDPE/PKS biocomposites had lower total weight loss. The thermal stability of the biocomposites was reduced due to the addition of filler loading.

Taro powder (TP) filled composites based on recycled high density polyethylene (RHDPE)/ ethylene vinyl acetate (EVA) were prepared via melt blending method. Polyethylene-grafted-maleic anhydride (PE-g-MAH) was used as a compatibilizer to enhance interfacial bonding of RHDPE/EVA/TP composites. The effects of TP loading and the addition of PE-g-MAH on the tensile properties and thermal stability of RHDPE/EVA/TP composites were investigated and studied. Findings indicated that increased TP loading will reduce tensile strength and elongation at break while increasing the modulus of elasticity. The thermal stability of RHDPE/EVA/TP composites improved by increasing filler loading. With respect to both tensile properties and thermal stability, RHDPE/EVA/TP composites with PE-g-MAH performed better than the composites without the addition of compatibilizers.

Nanocomposites with high density polyethylene (HDPE)/nanoclay/bamboo flour were fabricated by melt compounding. Their thermal behaviors and degradation kinetics of the composites with different clay contents were characterized through dynamic and isothermal Thermogravimetric (TG) analysis. It was found that the use of nanoclay improved the thermal stability of the composites. The nanolayers could act as a barrier for the degradation of HDPE/bamboo hybrids. The addition of compatibilizer also improved the thermal stability of HDPE/bamboo composites, but the effect was less significant than clay. It seems that there is no much difference in the thermal behaviors between HDPE/nanoclay/bamboo systems with and without the addition of compatibilizer. The activation energy values varied very little for different clay contents in the composites. Thermal decomposition process of HDPE/bamboo composites with various clay additions had similar TG curves.
