摘要：

Lamellar single crystals of chitosan were prepared at 125°C by adding ammonia to a low DP fraction of chitosan dissolved in water. The crystals gave sharp electron diffraction diagrams which could be indexed in an orthorhombic P212121 unit cell with a a 8.07 A ̊, b 8.44 A ̊, c 10.34 A ̊. The unit cell contained two anti-parallel chitosan chains and no water molecules. It was found that cellulose microfibrils from Valonia ventricosa could act as nuclei for inducing the crystallization of chitosan on cellulose. This produced a shish-kebab morphology. © 1990.
