Abstract: In this presentation, we succeed in altering polymer morphology using terahertz (THz) wave irradiation. Pulsed THz waves generated by a free electron laser (FEL) were irradiated to a poly(3-hydroxybutylate) (PHB) / chloroform solution during solvent casting crystallization. Morphological observation shows the formation of micrometer-sized crystals via the THz wave irradiation. Further, a 10–20% increase in crystallinity is observed through analysis of the infrared (IR) absorption spectra.
