Special Issue Information

Dear Colleagues,

Phase behavior of polymer materials has drawn much attention due to its strong relationship with the expressing materials’ properties, such as energy, mechanical, optoelectronic, drug release, sensing, catalyst, self-healing and so on. The phase behavior of material structures from nanoscale to microscale by self-assembly or top-down methods provides high feasibility of altering the properties of polymeric or hybrid materials. Unique polymer-based materials by controlling phase behavior through physical and/or chemical treatments could, therefore, exhibit specific properties superior to the current ones. This Special Issue will embody the innovative research articles that contain simulation, experiment and application fields of polymer-related materials in solution, gel and solid state. The integration of these investigations in this Special Issue may rapidly provide the relevant knowledge for readers and researchers who are interested in the recent research progress of the phase behavior of polymer materials, further inspiring brainstorms and the derivative inventive power of investigators. Articles associated with this emerging field, including the investigations of phase behavior of supramolecules, hierarchical organizations in different length scales, organic–inorganic hybrids, conducting polymers and liquid crystal polymers, in static or dynamic state with specific functions and the material properties, are welcome.

Polymerization was conducted in acetonitrile using benzyl chloride—boron trifluoride etherate initiating system. According to DSC data, the temperature range of melting [...] Read more.
A new method for purification of 2-methyl-2-oxazoline using citric acid was developed and living cationic ring-opening polymerization of 2-methyl-2-oxazoline was carried out. Polymerization was conducted in acetonitrile using benzyl chloride—boron trifluoride etherate initiating system. According to DSC data, the temperature range of melting of the crystalline phase of the resulting polymer was 95–180 °C. According to small-angle X-ray scattering and wide-angle X-ray diffraction data, the degree of crystallinity of the polymer was 12%. Upon cooling of the polymer melt, the polymer became amorphous. Using thermogravimetric analysis, it was found that the thermal destruction of poly(2-methyl-2-oxazoline) started above 209 °C. Full article
