PROMOTION OF POLYLACTID ACID ECO-FRIENDLY BY COMBINED ADDITION OF PCL CATECHIN-CHITOSAN UNDER EXTRUDING CONDITION

Biodegradable polymers are seen as a potential solution for the environment generated by plastic waste. The purpose of this study was to see the effect of adding a catalyst to the manufacture of PLA/PCL-Catechin-Chitosan as a raw material for making plastics . This research was carried out with variations in the addition of ZnO catalyst 0.1 % (PPXya), 0.2% (PPXyb) and 0.3% (PPXyc ). From the results of the analysis using Fourier Transform Infrared (FTIR) obtained stretching groups of OH, CO and C= O at wavelengths (3860, 1060 and 1753) cm-1 at the addition of 0.3% ZnO catalyst (PPXyc ). Based on the analysis of the thermal stability using Thermogravimetry (TGA) the decomposition temperature was obtained at 387℃ with the addition of catalyst 0.3% (PPXyc ). Morphological analysis using Scanning Electron Microscopy (SEM) showed that the surface structure of PLA was in the form of widespread lumps. The more concentration of additional catalyst used can affect the formation of PLA/PCL-Catechin-Chitosan. The result of the tensile test tensile analysus are greater the addition of ZnO catalyst in the sample PLA-PCL-Catechin-hitosan can to be able to increase the tensile value of the of the sample.
