摘要：

Disclosed herein is a method for preparing porous micron/nano-spherical hemostatic materials. An acidic solution of chitosan having a viscosity of about 8-212 cps is prepared. A spray drying process is carried out to convert the acidic solution of chitosan into particulates. The particulates are heat-treated at about 70-100℃ to obtain the porous micron/nano-spherical hemostatic materials.在此揭示一種用以製備多孔性微/奈米球狀止血材料的方法。配製幾丁聚醣的酸性水溶液,並使此酸性水溶液在室溫下的黏度為約8-212 cps。利用噴霧乾燥製程將上述幾丁聚醣的酸性水溶液製成球狀體材料。在約70-100℃下熱處理該些球狀體材料。
