The development of polymer membranes with tailored micro-morphol. and wettability is a demand in the areas of filtration, sensors, and tissue engineering, among others. The thermoplastic copolymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), is one of the most widely used polymers for these applications due to its good mech. and thermal properties, biocompatibility and low d. Although the control of the PVDF-HFP morphol. is a complicated task, the introduction of ionic liquids (ILs) in the PVDF-HFP matrix opens new perspectives in this area. This work consists of a systematic study of three different protic ionic liquids ([dema][TfO], [MIm][NTf2] and [MIm][Cl]) in the control of PVDF-HFP membranes properties. Different preparation conditions are also analyzed. These results demonstrate how several parameters such as morphol., water absorption capacity and mech. properties vary depending on the production methodol. employed and on the choice of incorporated IL. Pores of different sizes, spherulites and compact structures have been obtained, as well as hydrophilic and highly hydrophobic structures. These results show that ILs play a key role in the optimization of polymer properties and given the large number of available ILs, open up new possibilities for the development of polymer membranes suitable for applications where specific morphologies are desirable. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Reference of 35487-17-3).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Reference of 35487-17-3
