The conductivity and high surfacetovolume ratio of carbon nanofibers (CNFs) composited with the mediumchainlength poly3hydroxyalkanoate (mclPHA) have attracted much attention as smart biomaterial. However, poor CNF dispersion leads to tactoid agglomerated composite with poor crystallite morphology resulting in inferior thermomechanical properties. We employed acoustic soniion to
