Based on the work so far an exciting new area would involve PFS-b-PP (PP = polyphosphazene) block copolymers. These materials would possess a highly tuneable inorganic PP coblock, which is superficially reminiscent of PDMS. However, the PP block is inherently much more tuneable allowing hydrophobic /hydrophilic or crystalline / amorphous or high Tg / low Tg substituents to be attached at will due ...
