Using N-isopropyl-amide (NIPAAm) thermosensitive function material as monomer and nuclear track microporous membrane (NTMM) as baseline material

a thermosenstitive intelligent track membrane (TsITM) was prepared by the over-oxidization and pre-irradiation grafting techniques. The TsITM can be used to make a micro-switch controlled by temperature. The effects of pre-irradiation dose

grafting temperature

monomer concentration and reaction time on the grafting yield were investigated

and the dynamic range of responsive grafted track pores were observed. To obtain sub-micron responsive grafted track pores only a very thin thermosensitive layer is needed. The TsITM pores are capable of swelling and shrinking rapidly and respond more sensitively to temperature.
