Dopamine-modified alginate and gelatin were prepared. The polymers were characterized and the properties of their aqueous solutions were investigated. Aqueous solutions of dopamine-modified alginate and gelatin with a concentration exceeding 20 mg/mL naturally formed gels after 16 h. Although polydopamine itself was not used for template-assisted nanostructure formation, the modified polymers could be used with dopamine. Mixing with dopamine allowed the precise shape of the template to be maintained in the resulting material, allowing nanopatterned surfaces and nanotubes to be prepared.
制备了多巴胺改性的海藻酸盐和明胶。对这些聚合物进行了表征,并研究了其水溶液的性质。浓度超过20mg/mL的多巴胺改性海藻酸盐和明胶水溶液在16小时后自然形成凝胶。虽然聚多巴胺本身未用于模板辅助的纳米结构形成,但改性后的聚合物可与多巴胺一起使用。与多巴胺混合可使模板的精确形状在所得材料中得以保持,从而能够制备出纳米图案化表面和纳米管。
