用温控原子力显微镜对聚[(R)-3-羟基丁酸-co-10mol%-6-羟基己酸]薄膜在110℃的高温结晶过程中层状晶体的生长进行了原位成像。在片层的生长前沿观察到长度为100~500 nm、宽度为50~90 nm、厚度为6~8 nm的微纤丝晶体。在结晶过程中，这些微纤丝晶体沿片层的纵向生长。在某些情况下，观察到新形成的微纤丝晶体和分枝的微纤丝晶体。
In situ imaging of the development on lamellar crystals in thin films for poly[(R)-3-hydroxybutyric acid-co-10mol%-6-hydroxyhexanoic acid] was carried out at a high crystallization temperature of 110°C by temperature-controlled atomic force microscopy. The microfibril crystals with dimensions of 100–500nm length, 50–90nm width and 6–8nm thickness were observed at the growth front of lamellae. These microfibril crystals grew along the longitudinal direction of lamellae during crystallization. In some cases, newly formed microfibril crystal and branching microfibril crystal were observed.
