Computer simulations and numerical techniques for studying phase separation and interfacial properties of polymer blends and polymer-solvent mixtures are discussed and illustrated by a simulation study of coarsegrained models. The results of the simulation are quantitatively compared to the prediction of ...
本研究基于高聚物相分离的现有理论及实际应用前景,分别由高聚物不相容共混体系和有条件相容的高临界共溶温度体系制备出高聚物功能性的形状记忆材料及功能性多孔材料。 The research was based on the polymer phase separation and contained m...
8.3.1.2 Dynamics of Polymer-Polymer Phase Separation One of the most interesting features in the dynamics of liquid-liquid phase separation in binary mixtures is the ‘temporal universality’ of phase growth, originally developed for small molecule systems and subsequently extended to macromolecular syste...
We have studied the phase separation process in a mixture of a liquid crystal material and two different monomers undergoing a polymerization process. Phase equilibrium was theoretically analysed using a Van der Waals free energy density approach. Results indicate that the more slowly reacting monomer ...
作者: W Hu 摘要: The thermodynamic phase diagrams and their implications to the kinetics of phase separation in the polymer-based miscible multi-component systems have been introduced. In addition, the microphase... DOI: 10.1007/978-3-7091-0670-9_9 年份: 2013 收藏...
Computer simulations and numerical techniques for studying phase separation and interfacial properties of polymer blends and polymer-solvent mixtures are discussed and illustrated by a simulation study of coarsegrained models.

Rational design of dual Chemo- and Thermo-responsive phase separation of Poly(4-hydroxystyrene) in non-aqueous media Dual chemo- and thermo-responsive phase separations of poly(4-hydroxystyrene) in non-aqueous media were demonstrated. The addition of small amounts of hydrogen-bonding molecules as ...
In recent years the thermodynamics of polymer-polymer miscibility has been studied extensively in contrast to the rather scant attention received by the kinetics of phase separation. Page %P Close Plain text Look Inside Citations Other actions Reprints and Permissions Export citation About this...
一说到分离,首先比较容易联想到的是phase separation(如油水混合物)。但是这里的分离区别于phase separation. 一般来说是这种分离会成一种连续但组分不同的体系(③会解释)。看图↓ 这种分离并不会像油水混合物那样最终形成两个连续相,而是会一直保持这种状态 ...
