对高压环境中聚合物玻璃化转变温度(T_g)测量方法的现状与进展进行了综述.在常压测量法基础上发展起来的高压测量方法主要有:高压差示扫描量热法(HP-DSC)、蠕变柔量法等;原位光学法则是新近发展起来的一种非接触式测量方法.随着超临界流体技术与应用的发展及仪器科学自身的不断进步与完善,必将涌现出更多先进的测量技术与方法.
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 applications of supercritical fluid technologies and progress of instrument science.
