▎ 摘　　要

A novel biocomposite of poly(epsilon-caprolactone) (PCL) containing poly((R)-3-hydroxybutyric acid) (PHB) and a fixed amount of reduced graphene oxide (RGO) was synthesized. The characterization of the composite by Fourier-transform infrared, ultraviolet-visible spectral analysis, differential scanning calorimetry and thermogravimetric analysis indicates a strong interaction between PCL and PHB/RGO. Honeycomb-patterned thin films with regular structures were fabricated by casting the composite solutions under humid conditions. The temperature-dependent direct current (DC) conductivity of the patterned films was studied over the range of 290-335 K, revealing the semiconducting behavior of the transport properties of the composite films. The presence of the PHB component not only slightly increased the conductivity but also accelerated the biodegradability of the PCL matrix.
