Hierarchical honeycomb-structured films by directed self-assembly in "breath figure" templating of ionizable "clicked" PH3T-b-PMMA diblock copolymers: an ionic group/counter-ion effect on porous polymer film morphology

The self-assembly of 1,2,3-triazole and ionic 1,2,3-triazolium "clicked" poly(3-hexylthiophene)-b-poly(methylmethacrylate) (P3HT-b-PMMA) rod-coil diblock copolymers was used to fabricate honeycomb-patterned porous films via "breath figure" templating. The surface and inner morpho...

More Information
Summary:The self-assembly of 1,2,3-triazole and ionic 1,2,3-triazolium "clicked" poly(3-hexylthiophene)-b-poly(methylmethacrylate) (P3HT-b-PMMA) rod-coil diblock copolymers was used to fabricate honeycomb-patterned porous films via "breath figure" templating. The surface and inner morphologies of the honeycomb films can be both controlled by either ionizing the 1,2,3-triazole linker or changing the counter-ion nature.
