Surface modification of layered zirconium phosphate with PNIPAM

A new method was reported to modify layered zirconium phosphate (ZrP) with thermoresponsive polymer PNIPAM (poly N -isopropylacrylamide). PNIPAM was proved to be covalently grafted onto ZrP. 60 Co γ-rays irradiation produced peroxide groups on the surface which, upon heating, initiated free radical...

Description
Summary:A new method was reported to modify layered zirconium phosphate (ZrP) with thermoresponsive polymer PNIPAM (poly N -isopropylacrylamide). PNIPAM was proved to be covalently grafted onto ZrP. 60 Co γ-rays irradiation produced peroxide groups on the surface which, upon heating, initiated free radical polymerization and subsequent attachment of PNIPAM. A new method to surface modify layered ZrP with PNIPAM, and a covalently connection was formed between ZrP and PNIPAM.
