Monitoring Surface-ModificationSteps onPHBVFilmsby XPS. After each modification step, XPS was applied to characterize the modified surfaces to achieve the information on chemical structure and atomic concentration. Four different surfaces, namely, PHBV films (PHBV), NH3 plasma-treated PHBV films (PHBVNH2), MAL-PEG-grafted PHBV films (PHBV-PEGMAL), and RGD-modifiedPHBVfilms (PHBV-RGD) were analyzed byXPS. Table 1 lists the intensities (i.e., the measured peak areas divided by the corresponding sensitivity factors and normalized to 100% total intensity) of the elements on the four different surfaces. Therewas no nitrogen signal found on the PHBV surface. The nitrogen signal appeared after NH3 plasma treatment, and the intensities increased after subsequent reactions with bifunctional PEG and RGD peptides. |

用XPS監(jiān)控PHBV薄膜表面改性的步驟 每步改性后，用XPS對表面進行表征，分析化學(xué)結(jié)構(gòu)和原子比例。共分析了PHBV薄膜 (PHBV)、NH3 等離子體處理PHBV薄膜(PHBVNH2)、MAL-PEG嫁接PHBV薄膜(PHBV-PEGMAL)和RGD改性PHBV薄膜(PHBV-RGD)等4種不同的表面。表1給出了4種表面的各元素強度（即峰面積除以相應(yīng)的靈敏度因子并將總強度歸一化為100%）。PHBV表面沒有觀察到氮的信號。NH3 等離子體處理后，氮信號出現(xiàn)，且與雙官能團PEG和RGD多肽反應(yīng)后強度增大。 |
