Visualization of the Recrystallization of Solution‐Grown Poly[(R)‐3‐hydroxybutyrate] Lamellar Crystals

Morphological changes of solution‐grown poly(R)‐3‐hydroxybutyrate] lamellar crystals during heating were directly investigated by atomic force microscopy. The thickening of lamellar crystals was further visualized by enzymatic degradation of less‐ordered crystal regions in thermally treated lamellar crystals. The morphological changes of lamellar crystals induced by thermal treatment are due to recrystallization.
