缩合剂

Using water - soluble carbodiimide as condensation agent , biomacromolecules such as gelatin , collagen and chitosan were covalently grafted on the plla - g - pmaa membranes . solution of the biomacromolecules was further coated on the above membranes to increase the surface density of the biomacromolecules . this technology was designated " grafting and coating " method
为了将生物大分子化学接枝于plla膜表面，首先在plla膜表面接枝pmaa ，将羧基引入plla表面，利用水溶性碳化二亚胺edac作为缩合剂，与含有氨基的生物大分子反应，可将生物大分子如明胶、胶原和壳聚糖化学接枝在plla膜表面。
