【摘要】：近年來,由于在光學、電學和生化等領域具有廣泛的潛在應用,有序多孔反蛋白石結構薄膜的研究引起了人們的廣泛關注.但是其在制備過程中常常會形成一些無法控制的缺陷,限制了這類材料的普及和實際應用.通過使用兩種基質前驅體(正硅酸乙酯或絲素蛋白)與膠體小球混合共組裝,探究了二元體系共組裝法制備無裂痕反蛋白石結構薄膜的可行性.并用掃描電鏡和可見光譜對薄膜結構進行了表征.結果表明,對于正硅酸乙酯體系,在不影響膠體小球有序排列的條件下,正硅酸乙酯在小球間的空隙中發(fā)生溶膠凝膠轉變,與微球共同組裝成有序致密的整體,去除微球模板后,可以得到大規(guī)模(200μm)無缺陷有序的反蛋白石結構薄膜.而對于大分子絲素蛋白體系,由于它和膠體小球有較強的相互作用力,會抑制膠體小球的有序組裝,導致無法形成有序結構薄膜.對兩種二元共組裝體系進行了實驗探索,實驗結果不僅有助于人們了解共組裝方式的適用范圍,而且為設計和制備無缺陷反蛋白石薄膜提供了新的途徑.
[Abstract]:In recent years, due to extensive potential applications in the fields of optics, electricity and biochemistry, the research of ordered porous inverse opal thin film has attracted wide attention. However, it often forms some uncontrollable defects in the preparation process, limiting the popularization and practical application of this kind of material. By using two kinds of substrates before using it The feasibility of the two element system co assembly method to prepare the non fissure anti opal structure film was investigated. The structure of the thin film was characterized by scanning electron microscope and visible spectrum. The results showed that the colloidal beads were not affected in order in the order of the colloidal beads. Under the conditions, the ethyl orthosilicate has a sol-gel transition in the gap between the small spheres and is assembled with the microspheres together into an orderly and compact whole. After removing the microsphere template, a large scale (200 m) non defective and ordered inverse opal structure film can be obtained. For the large molecular silk egg white system, it has a strong interaction with the colloidal beads. The force, which inhibits the orderly assembly of the colloid beads, leads to the failure to form an ordered structure film. The experimental exploration of two kinds of two element Co assembly system has been carried out. The experimental results not only help people understand the scope of the application of the co assembly, but also provide a new way for the design and preparation of the defective opal film.
