摘要

在室温和远低于n -异丙基丙烯酰胺最低温度的条件下，利用高能伽马射线对单体进行同时聚合和交联，制备了热敏性聚n -异丙基丙烯酰胺凝胶。结果表明，只有在极低温度下（- 78℃）才对平衡吸水有显著影响，而在高剂量下也有显著影响。凝胶的力学性能还取决于剂量和合成温度。但温度效应随着吸收剂量的增加而消失。

Anisotropic stressed radiation induced synthesis of N-Isopropylacrylamide gel: Effect on swelling extent and types of waters

Thermosensitive poly (N-Isopropylacrylamide) gels were prepared by simultaneous polymerization and crosslinking of monomer using high energy gamma radiation at room temperature and at temperatures well below the LCST of N-Isopropylacrylamide. It was observed that at very low temperature (−78°C) only there is significant effect on equilibrium water uptake that too at significantly high dose. The mechanical properties of the gels also depend on the dose and synthesis temperature. But the temperature effect gets nullified as the absorbed dose increases.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
