The Preparation And Surface Modification Of Nanoparticles Which Have Multifunctions

According to the development of science, nanomaterals were widely used in many field, such as metallurgy, chemical industry, textile, light industry, electron, aviation, and so on. Because of the special property of nanomateral, it can be used in textile to make out different textile products which have different functions.The surface of nanoparticles ZnO, TiO₂ and antimicrobial powder etc. were modified by stearic acid , Span80 and tetrabutyl titanate. The stearic acid and tetrabutyl titanate were made to cling to the surface of the powder. The material can not only avoid the serious reunite but also convert the polar surface to unpolar surface, so that the nanometer powder can combine very well with the fiber macromolecule material. The textile added with the modified powder reached the request of antimicrobial powder and anti-ultraviolet radiation.We prepared zinc titanate by precipitator (NH₄)₂CO₃, Zn(NO₃)₂.6H₂O and tetrabutyl titanate as starting materials with methods of precipitation and microemulsion. The crystal structure and microstructure were...
