“…Previous studies have shown that the PLA matrix demonstrates good mechanical behavior; however, PLA alone is not sufficient to produce a favorable product (Lee and Wang 2006). Formerly, PLA composites improved the properties of composites through blends with low cost, renewable, and fully biodegradable natural fillers, such as wood flour, starch, lignocellulosic fibers/fillers, and natural cellulose fibers (Oksman et al 2003;Masud et al 2005;Anuar 2007;Salmah et al 2012). PLA has the advantage of being both renewable and biodegradable, since lactic acid is produced from biological processes.…”

The objective of this work was to study the biodegradability of polylactic acid (PLA)/paddy straw powder (PSP) biocomposites. Environmental degradation was evaluated by composting the biocomposite samples into the soil. Different techniques, including mechanical tests and scanning electron microscopy (SEM), were used to obtain a view of the degradation that occurred during the soil burial of the biocomposites. Results of the mechanical tests showed that an increasing content of PSP in the biocomposites decreased the tensile strength and elongation at break (EB), while it increased the modulus of elasticity after six months of exposure. Scanning electron microscopy on the surface after soil burial showed that the filler was poorly wetted by the matrix. This explains the reduction in tensile strength and the elongation at break after soil burial. Differential scanning calorimetry results indicated that the crystallinity of the biocomposites increased with longer composting periods.

“…Most researchers are more interested in the utilization of agricultural wastes such as corn cob , palm kennel shell (Salmah et al 2013), coconut shell (Chun et al 2012;Salmah et al 2012b), and chitosan (Salmah and Azieyanti 2011; to produce biocomposites that reduce cost as well as enhance the properties and biodegradability of biocomposites. Corn (Zea mays) is a biomass resource that is cultivated around the world.…”

Chitosan/Corn Cob Biocomposite Films by Cross-linking with Glutaraldehyde

Corn cob (CC) was used as a filler in chitosan (CS) biopolymer films. The effect of glutaraldehyde (GLA) as a crosslinking agent was studied in an effort to improve the properties of CS/CC biocomposite films prepared via solvent casting. The tensile strength and elongation at break values decreased, but the modulus of elasticity increased with CC content. However, the tensile properties of CS/CC biocomposite films improved when modified with GLA. The Fourier transform infrared (FTIR) results indicated the presence of imine bonds (C=N) and ethylenic groups due to the cross-linking reaction between CS and GLA. The thermal stability of CS/CC biocomposite films reduced with increasing CC content. The modification of CS/CC with GLA enhanced the thermal stability of the biocomposite films. Moreover, the wettability and adhesion of the CC-CS system were enhanced by modification with GLA, as demonstrated by a morphological study. The crosslinking agent glutaraldehyde positively affected the tensile strength, modulus of elasticity, and thermal stability of the biocomposite films.

“…The result found the fiber content increased, the elongation at break of PLA/DHF biocomposite decreased. In general, natural fiber is rigid material that not elongate much [18]. Thus, the addition of DHF would not contribute on the elongation of PLA matrix.…”

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.
