沉积压力对Parylene C膜性能的影响

采用X射线衍射(XRD),MOCON透湿仪等研究了不同沉积压力下制备Parylene C膜的结晶度、水蒸汽透过性、拉伸强度、雾度、透明度随沉积压力的变化规律。结果表明,随着沉积室压力升高,Parylene C膜相对结晶度、透湿性能、拉伸强度、透明度下降,雾度增大。

DSC Study of Thermal Properties of Biodegradable Poly(Butylene Succinate-co-terephthalate)

Poly （ butylene succinate ） （ PBS ）, poly （ butylene terephthalate） （PBT） and poly （butylene succirmte-coterephthalate） （PBST）s were synthesized from dimethyl succinate and/or dimethyl terephthalate reacting with 1,4- butanediol through a process of transesterification/ polycondmsation in the presence of a high effective catalyst and characterized by means of GPC and DSC. The investigation was mainly focused on the influence of content of terephthalate units on the molecular weight and thermal properties of resulting polymers. It is revealed that the melting temperature and crystallinity of synthesized polymers decrease first with the increase of terephthalate units, then shift to rise gradually by DSC measurements. The results of Flory equation suggest sequence structure of PBSTs is random.
