Double scale simulation of the cooling stage of semi-crystalline polymer melt 半结晶性聚合物熔体冷却过程双尺度模拟
Acoustic emission has been studied for a wide range of polymers including amorphous glasses, semi-crystalline polymers, copolymers, polymer blends and a crosslinked rubber during the course of uni-axial stretching at room temperature. 对一系列高聚物进行了单轴拉伸过程中声发射的观察,包括玻璃态高聚物、结晶高聚物、共聚物、共混高聚物和一种交联橡胶。
PMMA/ PEG blends are semi-crystalline polymer and the phase separations were occupied in blends system. Some PEG remained their crystal characterization, the other complex with PMMA networks, forming uniform amorphous phase. 有相分离发生,一部分PEG晶体依然保持其晶体的特征,另一部分PEG晶体转变成非晶态,与PMMA网络复合,形成完全均一的非晶相。
Composite polymer electrolytes, composed of lithium ionic conductive salt ( LiX) and semi-crystalline polymer, have been attracting research interests for its potential applications in rechargeable lithium batteries and other electrochemical devices. 聚合物电解质是由具有离子导电性的锂盐(LiX)与半晶态的聚合物基体复合形成的,在二次锂电池和其他电化学显示设备中有着巨大的潜在应用价值。
Research Advances on Miscibility of Semi-crystalline Polymer Blends Evaluated by Isothermal Crystallization Dynamics 由结晶动力学评价含结晶聚合物共混物相容性的研究进展
In a temperature jump from room temperature to 100 ℃ both amorphous and semi-crystalline polymers and polymer blends showed AE while not in the sudden cooling to-60 ℃. 非晶态、晶态高聚物或共混高聚物在突然升温到100℃时有声发射,但在突然降温到-60℃时却不出现声发射,这可能也说明声发射与高聚物试样内形成空洞有关。

Polypropylene is one of the most commonly used semi-crystalline polymer, and is one of the important material for li-ion battery microporous membrane preparation. 聚丙烯是一种常用的半结晶聚合物,是制备锂电池微孔膜重要材料之一。
Isotactic polypropylene ( iPP) is a kind of semi-crystalline polymer, the crystalline structure and perfection of which depends largely on the crystallization and annealing conditions. 等规聚丙烯(iPP)是一种半结晶性聚合物,它的结晶程度和结晶完整性在很大程度上依赖于结晶条件和后处理。
In actual processing of semi-crystalline polymers, the crystallization actually happens in polymer melt under temperature condition with varying cooling rates. The microstructures of the crystals are the key factors which determine the final aggregated structures and the properties of products. 半结晶聚合物在实际加工中,其熔体常常是在变速降温条件下冷却成型的,并伴随产生了晶体结构,这种微观结构往往是决定最终聚集形态和制品性能的关键因素。
