Polymer Material for the Construction of the Membrane with the Various Pore Sizes (a Critical Comparison of Various Synthesis Mechanisms)

TL;DRAbstract

The goal of this work was to prepare diblock-copolymer which rapidly changes its solubility in the dependency of the temperature. Appropriate diblock-copolymer should consist of one active (hydrophilic) component, and hydrophobic matrix block. The active component should have the switching temperature as close as possible to the human body temperature. Diblock-copolymer should exhibit sufficient mechanical stability, and the polydispersity index should be as low as possible. The mechanically stable components of the diblock copolymer were, polystyrene (PS) or poly(tert-butylmethacrylate) (PtBMA), while as an active component, poly-(2-(2ethoxy)-ethoxy)methoxy methatcrylate (PDEGMA) was used. A polymer required for this purpose should have molar mass of at least 150000 g/mol (in order to posses mechanical stability), and molar ratio of PDEGMA of 0.20–0.40 (in order to get desired structure of hexagonally packed cylinders of PDEGMA in the matrix). The syntheses were performed via differen
