Effect of PEG on the biodegradability studies of kenaf cellulose -polyethylene composites


Tajeddin, Behjat and Abdul Rahman, Russly and Abdullah, Luqman Chuah and Yusof, Yus Aniza and Ibrahim, Nor Azowa (2009) Effect of PEG on the biodegradability studies of kenaf cellulose -polyethylene composites. International Food Research Journal, 16 (2). pp. 243-247. ISSN 1985-4668; ESSN: 2231-7546


Several blends of cellulose derived from bast part of kenaf (Hibiscus cannabinus L.) plant, with different thermoplastics, low density polyethylene (LDPE) and high density polyethylene (HDPE), were prepared by a melt blending machine. Polyethylene glycol (PEG) was used as plasticizer. Biodegradability of these blends was measured using soil burial test in order to study the rates of biodegradation of these polymer blends. It was found that the cellulose/LDPE and cellulose/HDPE blends were biodegradable in a considerable rate. The bio-composites with high content of cellulose had higher degradation rate. In addition, biodegradability of the bio-composites made up using PEG was superior to those of the bio-composites fabricated without PEG, due to the improved wetting of the plasticizer in the matrix polymer. The results were also supported by the scanning electron microscopy (SEM).
