Conducting polymers have widely studied over the past decades owing to their high electrical conductivity and low-cost synthesis. Ice-templated approach was recently established as a facile method to prepare high-conductivity two-dimensional polymers, but the role of crystallinity of ice surface on the physicochemical properties of ice-templated conducting polymers remain elusive. In this study, we investigate the effects of ice crystallinity on the crystallinity and conductivity of ice-templated conducting polymers. For this, PEG-based oncotic agents were employed to control the crystallinity of ice systematically. Interestingly, the crystallinity of ice-templated conducting polymers bears a close resemblance to that of ice. This indicates molecular packing of conducting polymer chains is affected by the crystallinity of the underlying ice substrate. It was further revealed that highly localized polarons of conducting polymers decreased when synthesized on low-crystalline ice surface. |
