【摘要】：“復(fù)合型納米材料”是指兩種或兩種以上物質(zhì)在納米尺度上以某種方式結(jié)合在一起而構(gòu)成的復(fù)合粒子。通過多種材料的復(fù)合，實(shí)現(xiàn)性能互補(bǔ)和優(yōu)化，能夠制備性能優(yōu)異的納米材料。有機(jī)-無(wú)機(jī)雜化納米材料綜合了無(wú)機(jī)材料、有機(jī)材料和納米材料的優(yōu)良特性，在力學(xué)、熱學(xué)、光學(xué)、電學(xué)、生物以及環(huán)保等領(lǐng)域中展現(xiàn)出廣闊的應(yīng)用前景。由于聚苯乙烯特有的物理性質(zhì)及其實(shí)際應(yīng)用，尤其是在生物分離和檢測(cè)中的應(yīng)用，關(guān)于聚苯乙烯-無(wú)機(jī)納米復(fù)合材料的研究和應(yīng)用，正引起人們更廣泛的興趣。本文主要研究了有機(jī)-無(wú)機(jī)雜化納米材料以及磁性納米復(fù)合材料的合成。本課題按照以下幾個(gè)方面展開： 首先，本文研究了微觀形貌和分散性良好的四氧化三鐵/聚吡咯烷酮的制備，研究了Fe3O4的量、反應(yīng)時(shí)間和反應(yīng)溫度對(duì)復(fù)合粒子形成的影響。生成的產(chǎn)物用TEM、XRD、FT-IR和VSM等進(jìn)行表征，結(jié)果表明合成出來分散性良好，具超順磁性，粒徑為18.6nm的四氧化三鐵/聚吡咯烷酮復(fù)合粒子。 其次，研究了聚苯乙烯磁性微球的合成及羧基化修飾，，包括Fe3O4/聚苯乙烯、聚苯乙烯/甲基丙烯酸甲酯和Fe3O4/聚苯乙烯/甲基丙烯酸甲酯復(fù)合微球的合成，探索了MMA的量、乳化劑濃度和單體濃度對(duì)復(fù)合微球的影響。對(duì)于聚苯乙烯/聚倍半硅氧烷的合成，探索了不同酸濃度下合成的聚倍半硅氧烷和聚倍半硅氧烷與苯乙烯單體體積比對(duì)聚苯乙烯/聚倍半硅氧烷復(fù)合顆粒的影響。在乳液聚合中，當(dāng)乳化劑濃度為0.01M、St與MMA單體質(zhì)量比為20:1、Fe3O4粉體材料含量為1.0g時(shí)，成功制備出了粒徑均勻，分散性良好，粒徑大小為160nm的Fe3O4/聚苯乙烯/甲基丙烯酸甲酯復(fù)合微球。 最后，本文初步探索了Fe3O4/聚苯乙烯/甲基丙烯酸甲酯復(fù)合微球與急性心肌梗死（AMI）早期診斷指示物MYO抗體的連接，并采用了FT-IR和紫外分光光度法進(jìn)行檢測(cè)。實(shí)驗(yàn)結(jié)果表明，MYO抗體成功連接到了羧基化聚苯乙烯磁性微球表面，連接在復(fù)合微球表面的MYO抗體最佳濃度為1.3mg/mL。
[Abstract]:"Composite nanomaterials" refers to composite particles formed by two or more substances combined in some way at nanometer scale. Through the composite of many kinds of materials, the performance complementation and optimization can be realized, and the nanometer materials with excellent performance can be prepared. Organic-inorganic hybrid nanomaterials integrate the excellent properties of inorganic materials, organic materials and nanomaterials, and show broad application prospects in the fields of mechanics, heat, optics, electricity, biology and environmental protection. Due to the unique physical properties of polystyrene and its practical applications, especially in biological separation and detection, the research and application of polystyrene-inorganic nanocomposites are attracting more and more interest. The synthesis of organic-inorganic hybrid nanomaterials and magnetic nanocomposites was studied in this paper. This subject is carried out according to the following aspects: Firstly, the preparation of Fe _ 2O _ 3 / poly (pyrrolidone) with good morphology and dispersion was studied. The effects of the amount of Fe3O4, reaction time and reaction temperature on the formation of composite particles were studied. The synthesized products were characterized by TEMN XRDX FT-IR and VSM. The results showed that the composite particles of iron trioxide and polypyrrolidone with a particle size of 18.6nm were synthesized with good dispersion and superparamagnetism. Secondly, the synthesis and carboxylation modification of polystyrene magnetic microspheres were studied, including the synthesis of Fe3O4/ polystyrene, polystyrene / methyl methacrylate and Fe3O4/ polystyrene / methyl methacrylate composite microspheres, and the quantity of MMA was explored. Effects of emulsifier concentration and monomer concentration on composite microspheres. For the synthesis of polystyrene / polysilane, the effects of the volume ratio of polysilane and polysilane to styrene on the composite particles of polystyrene / polysilane were investigated. In emulsion polymerization, Fe3O4/ polystyrene / methyl methacrylate composite microspheres with uniform particle size, good dispersion and size of 160nm were successfully prepared when the mass ratio of emulsifier to MMA monomer was 20: 1, Fe _ 3O _ 4 was 1.0 g. Finally, the connection of Fe3O4/ polystyrene / methyl methacrylate composite microspheres with MYO antibody, an early diagnostic indicator of acute myocardial infarction (AMI), was preliminarily explored. FT-IR and UV spectrophotometry were used to detect the antibody. The results showed that the MYO antibody was successfully linked to the surface of carboxylated polystyrene magnetic microspheres, and the optimal concentration of MYO antibody attached to the composite microspheres was 1.3 mg / mL.
