ANTISTATIC PACKAGING OF PLASTICIZED BIODEGRADABLE POLYLACTIC ACID / GRAPHENE NANCOMPOSITES

Abstract

Poly lactic acid is inexperienced various to organic compound artifact plastics, employed in packaging with graphene that being one atom thick sheet, composed of sp2 carbon atoms organized in an exceedingly flat honeycomb structure .In this analysis victimization plasticizer thymol with composites were ready by an answer casting technique with (0.5-10) % towers Graphene .Experimental work contain morphological (AFM,FTIR), mechanical(Tensile, Tear, Hardness),electrical conductivity Color , contact angle, and TGA . Results hyperbolic electrical physical phenomenon with hyperbolic Graphene and makes the composite less resistive and appropriate to be used as antistatic packaging , increase the strength and tensile modulus and elongation at (0.5-1)% and attenuate in (3-10%)%,Tear Resistance attenuate once the tensile decrease however hardness hyperbolic with graphene .The results of contact angle of pure PLA is 83◦ that hydrophobic and attenuate to 51◦ at PLA/thymol/Graphene 10% percent to get hydrophilic that able to dissipate or promote the decay of electricity and improve method ability of device. Color and Brightness show that attenuate however appropriate for antistatic packaging and have become opacity at 100 percent Graphene. Thermal stability shows that Graphene hydrolysis by oxidization and exfoliation of carbon and also by the functionalization of sheets graphene to hence on the mass loss of composites.
