【摘要】：近年來,多孔材料在分離、過濾、吸附、生物工程及藥物靶向控釋等領(lǐng)域得到了廣闊的應(yīng)用。目前,有大量的方法可以制備多種多樣的有機(jī)或無機(jī)多孔材料,其中膠體晶體模板法是使用最為廣泛的。膠體晶體模板法制備的多孔材料孔分布均一、排列有序,并且可以通過調(diào)控膠體粒子的大小來調(diào)節(jié)孔徑,從而得到很多科學(xué)家們的廣泛關(guān)注。但是,大多數(shù)所制備的多孔材料的宏觀結(jié)構(gòu)都是很普通的,用在過濾分離需借助一定的裝置,操作復(fù)雜,而且功能性和智能性也需進(jìn)一步改善。本文在膠體晶體模板法制備多孔材料基礎(chǔ)上,通過結(jié)合氣息圖案法并改進(jìn)膜基質(zhì),控制膜的形態(tài),制備出了二元多孔結(jié)構(gòu)袋式多孔微濾膜,結(jié)合聚脲微球的沉淀聚合制備出了多孔聚脲微球,并分別探究了它們相關(guān)的應(yīng)用。另外利用模板法在玻璃管中制備了溫敏性微米級多孔反相柱,本論文主要的研究內(nèi)容可分為以下三方面:(1)結(jié)合氣息圖案法,控制聚合物溴化聚苯醚(BPPO)濃度及膠體粒子的尺寸,在燒結(jié)成球的毛細(xì)管一端的玻璃基質(zhì)上,制備出了底端具有二元多孔結(jié)構(gòu)的BPPO袋式多孔微濾膜。由于其特殊的袋狀結(jié)構(gòu),可以很方便的連接在注射器針頭上,二元孔結(jié)構(gòu)可以很好的過濾污水,在過濾分離,微注射等領(lǐng)域有較廣闊的應(yīng)用前景。(2)以丙酮和水作為溶劑,異佛爾酮二異氰酸酯(IPDI)作為單體,通過加入交聯(lián)劑三乙烯四胺(TETA)和二氧化硅(SiO2)納米顆粒,一步制備了交聯(lián)且表面多孔的聚脲微球(PPUM)。本章研究了SiO2納米顆粒的用量、粒徑尺寸以及交聯(lián)劑TETA對表面孔的形態(tài)、大小以及密度的影響。最后還深入探究了其對染料的吸附性能,對甲基橙及碘水溶液都有優(yōu)異的吸附功能,顯示了其在染料吸附處理等方面有重要的應(yīng)用前景。(3)在玻璃管中,利用膠體晶體模板法制備反相多孔聚苯乙烯柱,并引入溫度響應(yīng)聚合物異丙基丙烯酰胺(NIPAM),通過優(yōu)化實(shí)驗(yàn)條件,對溫度、NIPAM含量因素做了深入研究,利用自制的實(shí)驗(yàn)裝置來測量通過該反相柱的KCl溶液的電導(dǎo)率,以表征不同實(shí)驗(yàn)條件對反相柱孔徑的影響,為進(jìn)一步探索它的應(yīng)用做了鋪墊。綜上所述,本文在前人工作基礎(chǔ)上,通過改變多孔材料的宏觀及微觀結(jié)構(gòu),使其在應(yīng)用時(shí)更簡便高效,并探索了其功能性和智能性,對于設(shè)計(jì)和構(gòu)建新型分離、過濾、吸附材料及設(shè)備具有一定的參考意義。
[Abstract]:In recent years, porous materials have been widely used in the fields of separation, filtration, adsorption, bioengineering and drug targeted controlled release. At present, there are a large number of methods to prepare a variety of organic or inorganic porous materials, among which colloidal crystal template method is the most widely used. The porous materials prepared by colloidal crystal template method have uniform pore distribution and ordered arrangement, and they can adjust the pore size by regulating the size of colloidal particles, which has attracted many scientists' attention. However, the macrostructure of most of the prepared porous materials is very common, which requires a certain device for filtration and separation, complex operation, and further improvement of functionality and intelligence. In this paper, based on the preparation of porous materials by colloidal crystal template method, binary porous microfiltration membrane with porous structure was prepared by combining the breath pattern method and improving the membrane matrix to control the morphology of the membrane. Porous polyurea microspheres were prepared by precipitation polymerization of polyurea microspheres and their applications were explored. In addition, Templet method was used to prepare the thermo-sensitive micrometer porous reversed-phase column in glass tube. The main contents of this paper can be divided into three aspects: (1) the concentration of BPPO and the size of colloidal particles were controlled by the method of breath pattern. BPPO bag porous microfiltration membrane with binary porous structure at the bottom end was prepared on glass substrate at one end of the briquetting capillary. Because of its special bag structure, it can be easily connected to the syringe needle. The binary pore structure can filter sewage very well, and has a broad application prospect in the field of filtration, separation, microinjection and so on. (2) acetone and water are used as solvents. Isophorone diisocyanate (IPDI) was used as monomer and crosslinked polyurea microspheres (PPUM) were prepared by adding triethylenetetramine (TETA) and silica (Sio _ 2) nanoparticles in one step. In this chapter, the effects of the amount of Sio _ 2 nanoparticles, the particle size and the cross-linking agent TETA on the morphology, size and density of the surface were studied. In the end, the adsorption properties of the dye are also discussed. The adsorption of methyl orange and iodine aqueous solution is excellent, which shows that it has an important application prospect in dye adsorption treatment. (3) in glass tube, The reversed-phase porous polystyrene column was prepared by colloidal crystal template method, and the temperature responsive polymer isopropylacrylamide (NIPAM) was introduced. The electrical conductivity of the KCl solution passing through the reversed-phase column was measured by a self-made experimental device to characterize the influence of different experimental conditions on the pore size of the reversed-phase column, which paved the way for further exploration of its application. To sum up, on the basis of previous work, by changing the macro and micro structure of porous materials, this paper makes them easier and more efficient in application, and explores its function and intelligence, so as to design and build a new separation, filtration, The adsorption material and equipment have certain reference significance.
