所有样品均呈纤维堆叠形成的三维网络结构。与PLCL和PLCL/Gt表面相比,多巴胺(PDA)改性表面后的表现出一些纳米/微米颗粒,这主要归因于多巴胺聚合和PDA涂层。此外,所有改性后的表面粗糙度都有所增加。
All samples showed a three-dimensional network structure formed by fiber stacking. Compared with PLCL and PLCL/Gt surfaces, the modified surfaces exhibited some nano/micro particles attached on the nanofibers, which was primarily attributed to dopamine polymerization and PDA coating. Besides, all modified surfaces were relatively rough.
