Conjugated polymer based electronics, a type of flexible electronic devices, can be produced from solution by traditional printing and coating processes in a roll-to-roll format such as papers and graphic films. This low-cost flexible electronics show great promise for the emerging energy generation and conversion. The device performance of polymer electronics is largely dependent of crystalline structures of polymers. However, the solution crystallization kinetics of conjugated polymers in the presence of nanoparticles has not been fully understood yet. In this study, solution crystallization kinetics of poly(3-hexylthiophene) in the presence of carbon nanotubes and graphene oxide has been investigated by using in situ absorption spectroscopy. Effect of various kinetics parameters such as temperature, concentration, and particle loading will be discussed. The crystallization rate law and fold surface free energy will be addressed by using polymer crystallization theory of heterogeneous nucleation.
