Cellulose is a renewable carbon resource as well as an alternative material to replace petroleum-based plastics. Cellulose acetate butyrate(CAB), one of cellulose esters, is resistant to ultraviolet rays, has a lower moisture absorption than cellulose acetate and has an extremely high impact strength. However, it is susceptible to heat and has low flowability in the extrusion process. Poly(ethylene terephthalate) is a lightweight plastic that can be made into a number of different products and has impact resistant properties as well. In this work, Poly(ethylene terephthalate) (PET) and Cellulose acetate butyrate (CAB) were melt blended using twin screw extruder in order to improve properties of bio-based polymer and to enhance processability. The phase morphology of PET/CAB alloys was investigated by Field Emission Scanning Electronic Microscopy (FE-SEM). The compatibility of alloys was analyzed by Differential Scanning Calorimeter (DSC) and Dynamic Mechanical Analyzer (DMA). |
