Claims
- 1. A method for coating a glass surface with poly(N-isopropylacrylamide) comprising the steps of:
- (a) providing a glass surface,
- (b) bonding hydroxyl groups present in said glass surface to a silane coupling agent having a thiocarbamate group,
- (c) bringing a solution of a N-isopropylacrylamide monomer, a crosslinking agent, and a polar fluid, into contact with said thiocarbamate group in the presence of UV light thereby bonding and polymerizing said N-isopropylacrylamide monomer and crosslinking agent to form a layer of poly(N-isopropylacrylamide) bonded to said glass surface.
- 2. The method of claim 1 further comprising providing said glass as selected from the group consisting essentially of silicon dioxide, boric oxide, aluminum oxide, and phosphorus pentoxide.
- 3. The method of claim 1 further comprising providing said crosslinking agent as an organic molecule having an acrylamide group and at least two double bonds in said organic molecule's structure.
- 4. The method of claim 3 further comprising providing said crosslinking agent as N,N'-methylenebisacrylamide.
- 5. The method of claim 1 further comprising providing said polar fluid as selected from the group comprising acetone, water, ethanol, or combinations thereof.
- 6. The method of claim 1 further comprising providing said silane coupling agent as (N,N'-diethylamine)dithiocarbamoylpropyl-(trimethoxy)silane.
