Abstract
The coating of polyurethane devices was obtained by using a solution of a new heparin-adsorbing material, PUPA. The structure of the coated material was investigated at different depths by FTIR techniques. The bond with heparin is electrostatic, as revealed by subtracting the spectrum of the native PUPA from that of the heparinized sample.
摘要
聚氨酯装置的涂层是通过使用一种新型肝素吸附材料PUPA的溶液获得的。采用傅里叶变换红外光谱（FTIR）技术在不同深度研究了涂层材料的结构。通过从肝素化样品的光谱中减去天然PUPA的光谱发现，与肝素的结合是静电作用。
