摘要

以纤维素的乙酰化衍生物为原料，采用溶胶-凝胶法制备纤维素凝胶。凝胶的力学特性取决于凝胶的形成条件。用三种不同的方法对凝胶表面进行肝素化。凝胶抗血栓性的凝胶特性被发现依赖于偶联肝素的量。肝素化表面的血液凝固速度较慢，大约需要16个小时。

CELLULOSE GEL FOR BIOMEDICAL APPLICATION

Cellulose gel was prepared by the sol-gel method based on cellulose regeneration from its acetylated derivatives. The mechanical characteristics of the gel were foud depend on gel formation conditions. Heparinization of the gel surface was performed by three different methods. The gel antithrombogenic properties of the gel were foun to depend on the amount of coupled heparin. Blood coagulation on a heparinized surface is slower and takes about 16 hours.
