【摘要】：ZnO作為當前最具代表性的半導體氧化物材料,具有良好的生物相容性,并且在壓電傳感、氣體傳感、光電傳感等方面都具有非常出色的特性。然而目前國內(nèi)外針對氧化物半導體材料在生物電子領(lǐng)域的研究主要集中在非生物基底上,襯底材料不具備生物活性,限制了ZnO半導體材料的發(fā)展,如果能將ZnO可控的生長在具有生物活性的襯底材料上,可以為研制具有良好生物相容性及生物可降解性的電子元件打下良好基礎(chǔ),為開啟未來新型生物電子信息系統(tǒng)應用的大門提供了有利條件。本論文主要工作如下:1、玉米醇溶蛋白膜的制備與表征:采用了溶液滴涂的方法,制備ZnO生長所需的襯底材料玉米醇溶蛋白膜,并通過改變制備玉米醇溶蛋白膜的乙醇濃度、添加量、水浴捏合溫度、增塑劑含量以及成膜介質(zhì)等因素進行分組實驗,對不同條件下制備出的玉米醇溶蛋白膜進行表征,選擇出制備玉米醇溶蛋白膜的最優(yōu)條件。即玉米醇溶蛋白粉添加量為5g,選取的乙醇濃度為75%、添加量為40ml、水浴捏合溫度設定為75℃、增塑劑甘油及聚乙二醇-400添加量均為1.5g,成膜的襯底材料選擇OHP塑料膠片的情況下,制備出來的玉米醇溶蛋白膜的性能最佳,制備出的玉米醇溶蛋白膜的各項性能指標分別為:拉伸強度(TS)為6.1 MPa、斷裂延伸率(EB)為129.5%、水溶性26.25%、透光率79.2%。并且玉米醇溶蛋白膜的表面光滑且具備一定的韌性,可操作性較強,為下一步實現(xiàn)低溫下ZnO的可控性生長提供了良好的基礎(chǔ)條件。2、采用射頻磁控濺射的方法在玉米醇溶蛋白膜上進行ZnO的可控性生長:通過改變射頻磁控濺射設備的生長功率及氬氧比等條件,在玉米醇溶蛋白膜上生長ZnO薄膜材料,并利用場發(fā)射電子掃描顯微鏡(SEM)、光譜儀(PL)、原子力顯微鏡(AFM)、能譜儀(EDS)、X射線衍射儀(XRD)等測試手段對所制備的ZnO薄膜材料進行了表征并優(yōu)化實驗條件及工藝參數(shù)。在射頻濺射的真空度設為3.6×10-6Torr,氬(Ar):氧(O)為70:30,生長溫度為70℃,生長壓力(P)為8.2mTorr,功率為100W時,ZnO在玉米醇溶蛋白膜上生長成膜的效果較好。本文中成功實現(xiàn)了低溫下ZnO在玉米醇溶蛋白膜上的可控性生長,為今后制備和研究具有生物相容性的生物電子器件打下了良好的基礎(chǔ)。
[Abstract]:ZnO, as the most representative semiconductor oxide material, has good biocompatibility and excellent properties in piezoelectric sensing, gas sensing, photoelectric sensing and so on. However, the current research on oxide semiconductor materials in the field of bioelectronics is mainly focused on non-biological substrates, the substrate materials do not have biological activity, which limits the development of ZnO semiconductor materials. The controllable growth of ZnO on a bioactive substrate can lay a good foundation for the development of electronic components with good biocompatibility and biodegradability. It provides favorable conditions for the application of new bioelectronic information systems in the future. The main work of this thesis is as follows: the preparation and characterization of Zein film were as follows: Zein film, a substrate material for ZnO growth, was prepared by solution drip coating, and the ethanol concentration of Zein film was changed. The factors of adding amount, kneading temperature in water bath, plasticizer content and film forming medium were divided into groups. The Zein films prepared under different conditions were characterized, and the optimum conditions for the preparation of Zein films were selected. That is, the amount of corn alcohol soluble protein powder is 5 g, the concentration of ethanol is 75 ml, the addition amount is 40 ml, the kneading temperature of water bath is set at 75 鈩，
