【摘要】：近年來高分子材料發(fā)展迅速,功能高分子材料作為高分子材料中的一種,因其具有獨(dú)特的物理和化學(xué)特性,被廣泛應(yīng)用到生物、醫(yī)藥等重要的領(lǐng)域。隨著人們需求變得越來越高,新型的功能高分子材料成為人們研究的重點(diǎn)。介孔高分子材料具有較大的比表面積、有序的孔道結(jié)構(gòu)等特點(diǎn),在醫(yī)藥、化工和有機(jī)催化方面具有重要作用。本文的研究對(duì)象選擇了成本低、穩(wěn)定性高的介孔酚醛樹脂,通過負(fù)載金屬離子和基團(tuán)修飾來探究新型介孔材料的特性。前驅(qū)體材料酚醛樹脂采用水熱共聚工藝與一步還原技術(shù)以及揮發(fā)自組裝技術(shù)制備得到,并通過一系列表征驗(yàn)證其基本結(jié)構(gòu)和性能。針對(duì)該前驅(qū)體,本文做了兩個(gè)方面的研究。第一部分基于酚醛樹脂的強(qiáng)吸附性能和柔韌性,將其與硝酸銅采用物理共混法混合,并將其進(jìn)行研磨,利用其強(qiáng)吸附鍵得到新型納米金屬銅復(fù)合材料。該復(fù)合材料具有較好的催化性能,經(jīng)過多次套用,復(fù)合材料表現(xiàn)出穩(wěn)定的催化活性。第二部分借助一步還原技術(shù)和水熱共聚工藝,采用活性劑EO-PO聚醚型F127導(dǎo)向劑在堿性條件下誘導(dǎo)甲醛、苯酚和間硝基苯酚低聚物自組裝,得到介孔高分子納米小球,該材料具有高度氨基功能化的特點(diǎn),并且具有短孔道結(jié)構(gòu),對(duì)重金屬離子具有很強(qiáng)的吸附能力。本文制備的金屬銅復(fù)合材料具有較好的催化性能;制備的介孔高分子納米小球具有很強(qiáng)的吸附特性,和適用在金屬離子吸附場(chǎng)合,這兩種酚醛樹脂基高分子材料在制備和應(yīng)用過程都始終貫徹了綠色化學(xué)理念,對(duì)于推動(dòng)綠色化學(xué)的發(fā)展具有積極的意義。
[Abstract]:In recent years, polymer materials have developed rapidly. As one of the polymer materials, functional polymer materials have been widely used in biology because of their unique physical and chemical properties. Medicine and other important fields. As people become more and more demanding, new functional polymer materials become the focus of research. Mesoporous polymer materials have large specific surface area, orderly pore structure and other characteristics, in medicine, Chemical industry and organic catalysis play an important role. In this paper, mesoporous phenolic resins with low cost and high stability were selected. The properties of new mesoporous materials were investigated by modifying metal ions and groups. Phenolic resins were prepared by hydrothermal copolymerization one-step reduction and volatile self-assembly. The structure and properties of the precursor were verified by a series of characterization. Two aspects were studied in this paper. In the first part, based on the strong adsorption and flexibility of phenolic resin, it was mixed with copper nitrate by physical blending method. A new type of nano-metal copper composite was obtained by grinding and using its strong adsorption bond. The composite has good catalytic performance and has been applied for many times. In the second part, by means of one-step reduction technique and hydrothermal copolymerization process, formaldehyde, phenol and m-nitrophenol oligomer self-assembly were induced by EO-PO polyether guidance agent under alkaline conditions. The mesoporous polymer nanospheres were obtained, which have the characteristics of highly amino functionalization, short pore structure and strong adsorption ability to heavy metal ions. The prepared metal copper composite has good catalytic performance. The prepared mesoporous polymer nanoparticles have strong adsorption properties and are suitable for metal ion adsorption. These two kinds of phenolic resin based polymer materials have always carried out the green chemistry idea in the preparation and application process. It has positive significance for promoting the development of green chemistry.
