“…The char formation also contributed to high percentage of residue content of rPS/DHF composites. The similar findings regarding to effect of char formation influenced the thermal properties of composites also reported by others researcher [21][22]. In conclusion, addition of more fiber content increased the tensile strength and modulus of rPS/DHF composites increased, but decreased the elongation at break.…”

Abstract. Polystyrene foam is one of the major plastic waste that hardly to recycle. The present research is aims to recycle polystyrene foam as raw material to produce wood plastic composites (WPC). The WPC was produced from recycled polystyrene (rPS) and durian husk fiber (DHF) using melt compound and compression moulding processes. This paper is focus on effect of fiber content on tensile and thermal properties of rPS/DHF composite. The results found the tensile strength modulus of this WPC increased at higher fiber content, but elongation at break was reduced. However, this composites exhibited an early thermal degradation when subjected to high temperature and this was commonly found among WPC. The thermal degradation of rPS/DHF composites yielded high percentage of char residue due to char formation of DHF. Overall, the rPS/DHF composites with 60 phr fiber content able to achieved strength slight above 16 MPa without any chemical treatment additives. This indicates the rPS/DHF composites can be a potential WPC if further modify with to improve its strength.

“…It has been explored in many applications such as drug delivery systems, coating, tissue engineering, cosmetics, food packaging and agricultural industries [4,5]. Chitin is the second most abundant natural polysaccharide after cellulose [6][7][8]. Among of biopolymer, CS has been considered as one of the most promising materials for future in producing packaging materials because of its excellent properties, such as biocompatibility, biodegradability, and economic advantages.…”

The effect of corn cob (CC) content and crosslinking agent on tensile, morphological, thermal properties, gel fraction and enzymatic degradation of chitosan (CS)/corn cob (CC) biocomposite films was studied. Epichlorohydrin (EP) and adipic acid (ADP) as crosslinking agents were added to improve the properties of CS/CC biocomposite films. The addition of CC decreased the tensile strength and elongation at break, but increased the modulus of elasticity of CS/CC biocomposite films. The EP-modified CS/CC exhibited higher tensile and thermal properties than ADP-modified CS/CC. The formation of crosslinkages between CS and EP or CS and ADP was proven by Fourier transform infrared studies. The modified CS/CC biocomposite films with ADP and EP, respectively, showed better interface interaction, as demonstrated in scanning microscopy electron. Furthermore, the incorporation of CC in CS increased the weight loss of enzymatic degradation of biocomposite films. Moreover, EP-modified CS/CC shows better resistance to hydrolysis in a-amylase enzymatic degradation than ADP-modified CS/CC. The gel fraction of CS/CC biocomposite films increases with the increasing CC content, whereas the gel fraction of modified CS/CC with EP is higher compared to modified CS/CC with ADP. The novelty of our research showed that the modified biocomposite films with EP have the highest tensile and thermal properties, also gel content than others biocomposite films. The biocomposite films modified with ADP confer plasticization effect compared to unmodified and other modified biocomposite films.

“…The natural filler can be easily obtained from any agricultural crop and waste, for instance, corn cob [7], cocoa pod [8], coconut shell [3] and palm kernel shell [9]. The main benefit of natural filler very low cost, biodegradable, less abrasive to machine, and inexhaustible resources [10][11].…”

Abstract. Polylactic acid (PLA) is biodegradable thermoplastic that made from renewable raw material, but its high cost limited the application. Thus, addition of natural fiber can be effectively reduced the cost of PLA. This research is utilised natural fiber extracted from durian husk to made PLA biocomposites. This paper is focus on the effect of fiber content on tensile and thermal properties of PLA/durian husk fiber (DHF) biocomposites. The results found that the tensile strength and modulus of this biocomposites increased with increase of fiber content, but the strength still lower compared to neat PLA. Then, the elongation at break of biocomposites was expected decreased at higher fiber content. The PLA/DHF biocomposites with 60 phr fiber content exhibited tensile strength of 11 MPa, but it is too brittle yet for any application. The addition of DHF caused an early thermal degradation on PLA biocomposites. Then, the thermal stability of PLA biocomposites was decreased with more fiber content.
