Effect of Zinc Oxide Nanoparticles Concentration on the Mechanical Properties and UV Protection of In Situ Synthesized ABS Based Nanocomposites

摘要

A series of ABS/ZnO nanocomposites with different nanoparticles content were synthesized by mass-mass and mass-suspension processes. Because nanocomposites obtained through mass-suspension process had a greater impact resistance than those derived from mass-mass process, they were subjected to twin-screw extrusion. The extrusion led to a dramatic morphological change and increase in impact resistance, higher than 100% in most of the cases. On the other hand, the higher the ZnO content, the higher the UV blocking (>95% for 1 and 3% of ZnO) for both materials, before and after extrusion.
