| Abstract: | The most advanced methods and techniques used for measuring the glassy transition temperatures of polymers in high pressure gases, such as supercritical carbon dioxide, were reviewed. The representative methods include the high pressure differential scanning calorimetry (DSC) method, the high pressure creep compliance measurement technique, and the in situ optical measurement method, etc. It can be anticipated that more advanced measurement techniques will come forth, along with the development and applicat... |
