A large increase in thermal conductivity κ was observed in a P(VDF-TrFE) thin film annealed above melting temperature due to extensive ordering of polymer backbone chains perpendicular to the substrate after recrystallization from the melt. This finding may lay out a straightforward method to improve the thin film κ of semicrystalline polymers whose chain orientation is sensitive to thermal annealing.
