碩士 === 國立臺北科技大學 === 分子科學與工程系有機高分子碩士班 === 106 === In this study, we utilized a free radical polymerization method to synthesize a temperature/pH sensitive hydrogels with the temperature-sensitive monomer NIPAAm as the base, then added the pH sensitive monomer IAM and allyloxy-cyclodextrin to strengthening its structure. For adjusting the properties of hydrogels, we changing the ratio of IAM and allyloxy-cyclodextrin to achieve different performance for temperature/pH environment and increase its mechanical properties, in order to respond to the high application value of PNIPAAm and its extensions. We hope to improve the strength of the multifunctional hydrogels, and realize its development potential in recycling. The results of the DMA experiment proves that added Allyloxy-cyclodextrin can be effective in improving the weak mechanical properties of adding pH sensitive monomers. It can increase the stress by 30% compared with the original hydrogels and improve the water absorption to improve its performance.
