Multi-functional microcapsules produced by aerosol reaction

摘要

Multi-functional microcapsules with an n-octadecane(C18)core and a titania shell were prepared by a rapid aerosol process with a hydrothermal post-treatment.They had a high core loading of nearly 80% and a nanocrystalline shell of mostly anatase.Upon heating to induce C18 melting the enthalpy change was 92-97 J/g.They were found to have a photocatalytic activity to eliminate bacteria and react with mercaptans.They also provided UV-blocking.When applied to clothing by coating they are expected to promote wearer's comfort and skin health.
