摘要:
An antibiotic and deodorant material and a preparation method thereof are provided. At first, a mesoporous molecular sieve, a grafting agent and a solvent are reacted under a thermal flux system. The grafting agent has a structure of chemical formula I or II, wherein R1 and R2 are alkyl groups having 1 to 20 carbon atoms. The grafting agent can modify surfaces of the mesoporous molecular sieve. Then, the surfaces of the mesoporous molecular sieve are modified by silver ions. Finally, the mesoporous molecular sieve is reduced by a reducing agent to form an antibiotic and deodorant material.

A composition of a weather-resistant resin coating material is provided that comprises polyvinyl alcohol, metal oxide nanoparticles, a salt, a cross-linking agent and water. A manufacturing method of a weather-resistant resin coating material is also provided. First, a solution of polyvinyl alcohol and a solution of metal oxide nanoparticles are prepared. Then, these two solutions are mixed to form a mixture solution. A salt and a cross-link agent are added in the mixture solution. Finally, the mixture solution is stirred to form the weather-resistant resin coating material.
摘要:
A water-soluble polymer is used to change surfaces of the magnetic metal oxide nanoparticles to hydrophilic surfaces. The hydrophilic magnetic metal s oxide nanoparticles can be stably dispersed in a water matrix. Then, the hydrophilic magnetic metal oxide nanoparticles are mixed with hydrophilic resin, and a nanometer-scale uniform size of nanoparticles is maintained.
