Abstract
In this work, biodegradable composites from poly(lactic acid) (PLA) and oil palm empty fruit bunch (OPEFB) fiber were prepared by melt blending method. Prior to mixing, the fiber was modified through bleaching treatment using hydrogen peroxide. Bleached fiber composite showed an improvement in mechanical properties as compared to untreated fiber composite due to the enhanced fiber/matrix interfacial adhesion. Interestingly, fiber bleaching treatment also improved the physical appearance of the composite. The study was extended by blending the composites with commercially available masterbatch colorant.
Highlights
The majority of commodity plastics used today are made of non-biodegradable petroleum-based polymer [1]
The aim of this work is to study the influence of fiber bleaching treatment with hydrogen peroxide on the properties of poly(lactic acid) (PLA)/oil palm empty fruit bunch (OPEFB) composite
The results demonstrate an improvement in impact strength for bleached fiber composites compared to the untreated fiber composite
Summary
The majority of commodity plastics used today are made of non-biodegradable petroleum-based polymer [1]. The persistence of these materials in the environment beyond their functional life has. Concern about the growing environmental issues and preservation of natural resources has stimulated the interest in biodegradable polymers based on renewable resources. Bio-based polymers offer environmental-friendly benefits as they have the capability to degrade naturally into organic substances without releasing any toxic components [2]. There are numbers of bio-based polymers that have been introduced commercially and available in the market. Poly(lactic acid) (PLA) attracts enormous attention because of its versatility, biocompatibility and biodegradability characteristics
