Abstract
The development of bioplastic composites from various natural polymers reinforced with Precipitated Calcium Carbonate (PCC) has become a field of increasing interest. In this study, the effect of PCC on the physical, mechanical and thermal properties of a cassava starch matrix composite was examined. The bioplastic composites were made of cassava starch and mixed with glycerol as a plasticizer and 0-10% by weight of PCC. The material was then poured into a mold and oven dried. The physical, thermal and mechanical properties of bioplastic/PCC composites were investigated using Tensile Strength measurements, X-Ray Diffraction, Thermogravimetric Analysis, Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR). The optimum tensile strength was obtained upon the addition of 4 % PCC. The addition of PCC improved the thermal stability of bioplastic/PCC composites. The results of X-ray Diffraction testing showed an increase in the crystallinity of the bioplastic/PCC composites with increase in PCC content but there is a decrease in the moisture absorption. SEM images indicated that the PCC filler content was incorporated into the matrix. In general, FTIR indicated the bioplastic/PCC composites were hydrophilic and the addition of PCC reduced the hydrophilic properties by damaging the hydrogen bonding between starch molecules and water.
