Surface photo-anchored PNIPAM crosslinked membrane on glass substrate by covalent bonds

- PNIPAM covalently fixed on the glass surface to increase its adhesion.
- The existence of TMPTA resulted a higher LCST value compared with PNIPAM alone.
- PNIPAM still showed good thermo-sensitivity after fixed on the surface of glass.
- Due to the property of discoloration with different temperature, PNIPAM membrane grafted on the surface of glass substrate had potential applications as temperature control switch device.
