【摘要】：利用球盤接觸形式的光干涉膜厚測(cè)量試驗(yàn)機(jī),研究了周期沖擊載荷作用下蛋白質(zhì)水溶液在材料表面的吸附膜生長(zhǎng)特性.對(duì)比了溶液蛋白質(zhì)組分、親疏水對(duì)偶表面和沖擊條件對(duì)球盤接觸區(qū)蛋白質(zhì)吸附膜厚的影響.結(jié)果顯示動(dòng)態(tài)沖擊下蛋白質(zhì)的吸附膜厚要遠(yuǎn)高于靜態(tài)吸附,吸附膜不斷在接觸區(qū)生長(zhǎng),之后趨于穩(wěn)定.金屬鋼球比陶瓷球、疏水盤表面比親水盤面,均更有利于蛋白質(zhì)吸附膜的生長(zhǎng).同時(shí)發(fā)現(xiàn)吸附膜厚與單一蛋白質(zhì)的濃度關(guān)系不大,卻和蛋白質(zhì)種類關(guān)系很大,球蛋白比白蛋白具有更好的吸附成膜性能.
[Abstract]:The adsorption film growth characteristics of protein aqueous solution on the surface of materials under periodic shock loading were studied by means of the optical interference film thickness measurement machine in the form of ball disk contact. The effects of solution protein composition, hydrophobic surface and impact conditions on the thickness of the protein adsorption film in the contact zone of the ball disk were compared. The results show that the adsorption film thickness of protein under dynamic shock is much higher than that of static adsorption, and the adsorption membrane grows continuously in the contact area and then tends to stabilize. The surface of the hydrophobic disk is more favorable to the growth of the protein adsorption membrane than that of the ceramic ball and the hydrophilic surface of the hydrophobic disk. At the same time, it was found that the thickness of the adsorbed membrane was not related to the concentration of single protein, but to the type of protein, and globulin had better adsorption performance than albumin.
