This paper describes a method for preparing chitosan fibers modified with hydroxyapatite (HAp), tricalcium phosphate (β-TCP), and HAp/β-TCP nanoparticles. Fiber-grade chitosan derived from the northern shrimp (Pandalus borealis) and nanoparticles of tricalcium phosphate (β-TCP) and hydroxyapatite (HAp) suspended in a diluted chitosan solution were used in the investigation. Diluted chitosan solution containing nanoparticles of Hap/β-TCP was introduced to a 5.16 wt% solution of chitosan in 3.0 wt% acetic acid. The properties of the spinning solutions were examined. Chitosan fibers modified with nanoparticles of HAp/β-TCP were characterized by a level of tenacity and calcium content one hundred times higher than that of regular chitosan fibers.
本文描述了一种制备用羟基磷灰石(HAp)、磷酸三钙(β-TCP)和HAp/β-TCP纳米颗粒改性的壳聚糖纤维的方法。本研究使用了源自北方虾(北方长额虾)的纤维级壳聚糖以及悬浮在稀释壳聚糖溶液中的磷酸三钙(β-TCP)和羟基磷灰石(HAp)纳米颗粒。将含有Hap/β-TCP纳米颗粒的稀释壳聚糖溶液引入到壳聚糖在3.0 wt%乙酸中的5.16 wt%溶液中。对纺丝溶液的性能进行了检测。用HAp/β-TCP纳米颗粒改性的壳聚糖纤维的特征在于其强度水平和钙含量比普通壳聚糖纤维高100倍。
