Effect of hybrid reinforcement of nanoclay and silica on properties of poly(lactic acid)
摘要
Abstract
PLA was adopted as a polymeric matrix to prepare PLA/nanoclay composites.The effect of the amount of nanoclay together with 2 phr SiO2 as a hybrid reinforcement on the structures and properties of the composites were inves-tigated.The results indicated that the crystallization behaviors,melt processability,mechanical toughness,and gas barri-er property of the PLA composites were significantly improved.The PLA composite with 2 phr SiO2 and 4 phr clay ex-hibited good filler dispersion,ductile fracture,and good gas barrier property.Compared to pure PLA,the PLA compos-ites presented an increase in elongation at break by 151%and in impact strength by 74.1%.Their oxygen and water va-por permeability coefficients were reduced by 67.4%and 65.0%,respectively.The excessive amount of clay was dis-advantageous to the toughness and also generated a slightly influence on gas barrier.关键词
