The results showed that the glass transition temperature and vicat softening point increased obviously with the increase of the content of the terpolymer. 结果表明:随共聚物用量的增加,共混物的玻璃化温度和维卡软化点明显提高;
The glass transition temperature Tg, melt point Tm, thermogravimetric curve, tensile strength and degradation rate of this blend were determined by DSC, TGA, tensile test and degradation test. 用差示扫描量热法、热重分析法和拉伸试验法等测定了CDA&PLLGA的玻璃化温度、熔点、热失重性能、拉伸强度和降解性能。
The results show that the wettability of the grafted PET fiber was improved remarkably and the grafted fiber had a good durability. The glass transition point of the grafted fiber was not observed by DSC analysis. 结果表明:Ar等离子体引发接枝后,丙烯酸单体接枝到涤纶纤维表面,纤维润湿性能显著提高,其耐久性良好,纤维玻璃化转变消失。
And the obtained antibacterial PET fiber had the antibacterial efficiency above 99% against staphylococcus aureus and coliform bacillus and showed lower strength and crystallinity, higher glass transition temperature and almost unchanged melting point and crystallization temperature, as compared with PET fiber. 抗菌PET纤维较PET纤维强度和结晶度有所下降,玻璃化转变温度有所提高,熔点和结晶温度变化不大。

The composite's glass transition point ( Tg) increased with the fiber content. 复合材料的玻璃化转变温度(Tg)随纤维用量增加而增大。
Results show that the glass transition point T_g and crystallization temperature T_o, increase but the crystallization rate decreases with the increase of As content. 实验结果表明:砷蹄系统的玻璃转业点Te和初始析晶温度T(er)随砷浓度增加而升高,而析晶速率则减慢;
It is also demonstrated that the thermal history conditions seriously influence the solidification microstructures and their effects are mainly demonstrated after the glass transition point. 结果还显示出,热历史条件对微结构转变有严重影响,且其作用主要是在玻璃转变温度点Tg以后才显示出来。
Thermal analysis results showed that there was no influence of POE and SiO2 on the glass transition temperature and melting point of PLA. 热分析研究结果发现,弹性体POE和无机纳米SiO2粒子对PLA的玻璃化转变温度和熔点的影响不大。
