    摘要:

    考察了酸堿處理多孔鈦、堿熱處理多孔鈦及未改性多孔鈦對(duì)牛血清白蛋白的等溫吸附行為，探討了多孔鈦表面改性對(duì)其蛋白質(zhì)吸附性能的影響。并通過掃描電子顯微鏡、X射線衍射儀、臺(tái)階儀、接觸角測(cè)量?jī)x等分別考察了3種樣品表面形貌、相組成、粗糙度及潤(rùn)濕性等性質(zhì)。結(jié)果表明，表面改性后多孔鈦的表面形貌、相組成、粗糙度及潤(rùn)濕性等性質(zhì)均發(fā)生了明顯改變，蛋白質(zhì)吸附性能得到了顯著提高。

    Abstract:

    The bovine serum albumin (BSA) adsorption character of pure porous titanium (PPT), acid-alkali treated porous titanium (AAPT) and alkali-heat treated porous titanium (AHPT) was investigated. The effect of surface modification on the protein adsorption behavior of porous titanium was discussed. In addition, the surface properties of the samples, including surface morphology, phase composition, roughness and contact angles, were examined by SEM, XRD, stylus profiler and contact equipment, respectively. Results show that after surface modification all the surface properties of the porous titanium change obviously, and the protein adsorption ability is enhanced evidently.
