Use of Epoxidized Waste Cooking Oil as Bioplasticizer of Sago Starch-Based Biocomposite Reinforced Microfibrillated Cellulose of Bamboo

Abstract

Transformation of waste cooking oil into bioplasticizer can be wisely converted by epoxidation with peroxyacetic acid and acid catalysts due to highly unsaturated triglyceride. This paper was aimed to investigate performance of epoxidized waste cooking oil (EWCO) as bio plasticizer of starch-based biocomposite reinforced microfibrillated cellulose of bamboo (MFC) based on tensile strength, and thermal stability by TGA. All of bamboo MFC was prepared through cellulose isolation by chemical treatments and microfibrillated cellulose conversion by assistance of ultrasonic homogenizer. The result showed that EWCO can increase the mechanical performance up to 10.7 MPa of EWCO 0.6% in 3% of MFC while by using glycerol 1.5% the biocomposite attained 1.9 MPa.
