Regular spherical silicone oil/SiO2 nanocapsules were prepared by template method and sol gel method in oil in water(O/W)lotion system with dimethyl silicone oil as the core material and silicon dioxide(SiO2)as the wall material.And the prepared nanocapsules were added into MC nylon to prepare MC nylon/nanocapsule composite materials.The structure of nanocapsules was characterized using FTIR,SEM and TEM,and the properties of the composite materials were measured using DSC,TG,SEM,electronic universal testing machine,digital impact testing machine,and DIN wear test.The experimental results showed that,the stability of the material was improved by the addition of nanocapsules,with a higher thermal decomposition temperature than the pure sample.when the addition amount of silicone oil/SiO2 nanocapsules was 0.2％,the tensile strength of the composite material increased by 24.11％;When the addition amount of silicone oil/SiO2 nanocapsules was 0.3％,the wear performance and impact strength were the best,with a decrease of 29.5％in wear and an increase of 49.82％in impact strength.
