摘要
本文简要地介绍了热释电流(TSC)法的基本原理,并结合自己的工作体会,着重讨论了用TSC法研究高聚物驻极体的玻璃化转变,研究对象包括均聚物(有无添加剂、交联、未交联)、共聚物(无规、嵌段)以及共混物。同其它的测试玻璃化转变的技术相比较,TSC法具有简便、灵敏和分辨能力高等特点。
Thermally Stimulated Current (TSC) method as a new technique in studying glass transition of polymers was reviewed and discussed. The TSC spectra of a series of polymer electrets, involving homopolymers, copolymers (random, block) and polyblends, were analyzed and studied in detail. Compared with differential scanning calorimeter (DSC) and dynamic mechanical test technique, TSC is a simpler and more sensitive method for inve-stigatting glass transition of polymers.
