纳米SiO_2对聚醋酸乙烯乳液的粒子形态和力学性能的影响

Effect of nano-silica on morphology and mechanical property of polyvinyl actate composite emulsion

采用原位聚合法制备了聚醋酸乙烯/纳米SiO2复合乳液,对乳胶粒的形态、复合乳液的力学性能进行了表征。结果表明,复合乳液力学性能有较大提高、微观形态更趋复杂,并对其机理进行了一定的分析。

Polyvinyl aeetate/nano-silica composite emulsion was prepared by in-situ polymerizatiorL The morphology and mechanical property of polyvinyl acetate/ nano-silica composite emulsion were characterized. The results showed that the mechanical strength of composites was improved , and particles morphology became more complicated. The mechanisms were also analysed.
