Abstract
In my study, it was mainly composed of two major parts. The polymer materials were designed to be with high water vapor transmission rate and well mechanical properties. In the first part, both PEG(poly(ethylene glycol)) and PPG(poly(propylene glycol)) acted as the soft segment were introduced into the procedure of synthesizing polyurethane. We could find the influences of various molar ratio of PEG and PPG on their thermal property, mechanical property, water vapor transmission rate, biocompatibility, and so on. In the second part of the study, it was followed by the first part. By using the PPG triol (Poly(propylene glycol) triol) and changing the molar ratio of polydiols, different star-shaped polyurethane hydrogel were produced. To see the performance of polyurethane hydrogel, thermal property, water vaper transmission rate, adhesion and so forth were analysized.
