by solution polymerization on 50℃. The swelling behavior
thermal properties and
magnetic properties were investigated. The test results showed that the hydrogels formed a stable IPN interpenetrating network structure and exhibited temperature sensitivity
pH sensitivity and paramagnetism. Below 31℃ the swelling ratios of the semi-IPN hydrogels increased with increasing of temperature
but above 31℃
the temperature sensitivity of the semi-IPN hydrogels slight decreased with increasing of temperature. However
the thermal shrinkage of NIPAAm hydrogels is successfully overcome.
