在本文中，我们创建的纳米杂化物由伊毛戈兰纳米管和各种脂肪族聚酯通过疏水化的伊毛戈兰。首次实现了通过伊毛戈兰上的铝醇基团与苯甲醛中的醛基之间的共价键合使伊毛戈兰疏水化。疏水化的伊毛戈兰与脂肪族聚酯具有良好的混溶性，并且它们的混合物通过它们的氯仿分散体的流延形成透明膜。将疏水化的伊毛沸石添加到脂肪族聚酯如聚（1-乳酸）、聚（ε-己内酯）和聚（琥珀酸丁二醇酯）中，引起聚合物膜的增塑，这应该是通过聚合物链在疏水化的IG上成核而引起的聚合物晶体的小型化。特别是，聚（L-乳酸）和疏水化伊毛沸石的纳米杂化物在拉伸下显示出定向结晶。
In this paper, we created nanohybrids consisted of imogolite nanotube and various aliphatic polyesters through a hydrophobization of imogolite. The hydrophobization of imogolite via covalent bonding between aluminol group on imogolite and aldehyde group in benzaldehyde was firstly achieved. The hydrophobized imogolite is well miscible with aliphatic polyester and their mixture forms the transparent films via casting of their chloroform dispersion. An addition of hydrophobized imogolites to aliphatic polyester such as poly(l-lactic acid), poly(ε-caprolactone), and poly(butylene succinate) brought about the plasticization of polymer films that should be induced by the miniaturization of polymer crystals via the nucleation of polymer chains on hydrophobized IGs. Especially, the nanohybrids of poly(l-lactic acid) and hydrophobized imogolite showed an oriented crystallization under stretching.
