Salt induced effect on block copolymer phase transition and its conductivity was examined using small angel x-ray scattering (SAXS), transition electron microscope (TEM) and AC impedance. Complex, composed of asymmetric disorder PS-b-P2VP and LiClO4, undergoes various morphological changes such as sphere (BCC), cylindrical (HEX) and lamella (LAM) in disorder block copolymer with selective ionic coordination to the nitrogen units of P2VP block. Both the transitions, Order-to-disorder (ODT) and order-to-order (OOT) transitions, were observed by varying the interaction parameter between the blocks and volume fraction of P2VP block, where the interaction parameter is inversely proportional to temperature. |
