Solvent-cast Biofilm from Poly(lactic) Acid and Durian Husk Fiber: Tensile, Water Absorption, and Biodegradation Behaviors
The issues of petroleum-based plastics are increasing day by day, causing environmental and health impacts.

description | The issues of petroleum-based plastics are increasing day by day, causing environmental and health impacts. One of the alternative ways to reduce these issues is to introduce a new biocomposite material in order to replace the commercial plastics. Poly(lactic) acid (PLA)/durian husk fiber (DHF) biofilms with different DHF contents (0, 5, 10, 15, and 20 wt%) were prepared via a simple solvent casting method. The tensile, water absorption, and biodegradation properties of the PLA/DHF biofilms were investigated. The results revealed that the tensile strength and modulus of elasticity of the PLA/DHF biofilms increased with increasing DHF content from 5 wt% to 10 wt%. However, the opposite results were shown in elongation at break. The tensile strength and modulus of elasticity of the PLA/DHF biofilms decreased as compared to neat PLA film due to the plasticized effect that happened in the biofilms. However, the enzymatic degradation with α-amylase and water absorption properties of the PLA/DHF biofilms increased with increasing of DHF content. Furthermore, alkali treatment with sodium hydroxide (NaOH) was carried out on the DHF. The NaOH treatment enhanced the tensile strength and water resistance of the biofilms, but reduced the enzymatic degradation of the biofilms. |
