Abstract
A method for treating a fabric for ultraviolet radiation protection is disclosed which comprises the steps of adding zinc oxide nanoparticles to a solution of 3-glycidyloxypropyl-trimethoxysilane, adding silicon dioxide to the mixture of zinc oxide nanoparticles and 3-glycidyloxypropyl-trimethoxysilane, placing a fabric in the mixture of zinc oxide nanoparticles, 3-glycidyloxypropyl-trimethoxysilane, and silicon dioxide, curing the fabric, and washing the fabric.
Claims11
A method for treating a fabric for ultraviolet radiation protection comprising the steps of:
- suspending zinc oxide nanoparticles in a mixture of an aqueous buffer and an organosilane or phosphonate with a reactive group, adding multidentate ligand to form a durable reactive layer on the zinc oxide nanoparticles, and adding an oxide, alkoxide, or salt of a metal other than zinc to form a surface layer of an oxide other than zinc on the zinc oxide nanoparticles;
- collecting the zinc oxide nanoparticles by centrifugation;
- washing the collected zinc oxide nanoparticles;
- re-suspending the zinc oxide nanoparticles in a buffer;
- adding the zinc oxide nanoparticles in the buffer to a solution of 3-glycidyloxypropyl-trimethoxysilane;
- adding silicon dioxide to the mixture of zinc oxide nanoparticles and 3-glycidyloxypropyl-trimethoxysilane;
- placing a fabric in the mixture of zinc oxide nanoparticles, 3-glycidyloxypropyl-trimethoxysilane, and silicon dioxide;
