Investigation Of Physical Properties Of Poly(Lactic Acid)/Eggshell Powder Composite Films

In this work, the effects of Chicken egg shell powder (ESP) on properties Poly(Lactic Acid) PLA/ESP composite films (products) were examined. 4 wt.% PLA solution prepared and ESP added to at wt. %10, %20, %30, %50. by film-casting method. The mechanical thermal behaviours composites investigated using fourier transform infrared spectroscopy (FTIR), xray diffraction analysis (XRD), thermogravimetric (TGA), dynamic mechanic anaylsis (DMA) polarized optical microscopic analysis. While in different amounts into film also increases crystal density as amount substance increases. Also, product increased, stability a sharper roughness structure is occurs. % 10 20 had elasticity PLA, while high-strength formation was observed 30 %50 composites. So, storage modulus seen higher level than normal PLA. These could be used packaging application because reducing light permeability formation.
