The results show that the hydrophilicity of PLA film is improved by introduction amido: the contact angle decreases from 78° to 56° and the free energy increases from 42.7mJ/m^2 to 51.4mJ/m^2. Compared with the control, osteoblast spread out more filopodia after 3 d incubation on amidation surface, and it entered cell division phase more quickly, which indicated that the surface amidation could promote the cell's adhesion and proliferation on the PLA film.

结果表明，酰胺基的引入改善了PLA膜的表面亲水性，其表面水接触角由78°减少到56°，自由能由42.7mJ/平方公尺增大到51.4mJ/平方公尺；与对照组相比，成骨细胞在改性表面培养3d后有大量的丝状伪足伸出，并且较快地进入了细胞分裂期，表明PLA膜表面的酰胺化能够促进细胞的黏附和增殖。
