1Influence of surface modification of SrFe12O19 particles with oleic acid on magnetic microsphere preparation显示文摘Oleic acid was used as surface modification agent to improve the hydrophobicity of magnetic strontium hexaferrite particles.The structure and properties of treated magnetic particles were characterized by scanning electronic microscopy(SEM),Fourier transform infrared spectra(FTIR),powder X-ray diffraction(XRD) and magnetic property measurement system(MPMS).The results show that oleic acid is chemically enwrapped on the surface of SrFe12O19 particles.Magnetic particles modified by oleic acid are highly dispersible and strongly responsive to magnetism but with slight decrease in saturated magnetization.The affinity between magnetic particles and monomers is improved by surface modification,resulting in increased particle incorporation in magnetic polymeric microspheres.The surface modification mechanism of magnetic particles by oleic acid is addressed in this work.Sifang Kong Peipei Zhang Xiufang Wen Pihui Pi Jiang Cheng Zhuoru Yang Jing Hai 2008Particuology2008,6,3:7
2Improved performance of aluminum pigments encapsulated in hybrid inorganic-organic films显示文摘An organic silane acrylate resin(PMBK) was synthesized by free-radical solution polymerization using methyl methacrylate,butyl acrylate and(3-methacryloxypropyl)trimethoxysilane as monomers.Aluminum(Al) particles were then encapsulated in inorganic-organic hybrid films that were prepared by hydrolysis and condensation of PMBK and tetraethyl orthosilicate(TEOS) on the surface of Al pigments.Characterization results showed that PMBK and TEOS could simultaneously hydrolyze and condense with hydroxyl groups on the surface of the Al particles to form composite Al particles coated with inorganic-organic hybrid films.Compared with raw Al particles,the corrosion resistance and adhesive properties of paint films containing the composite Al particles were improved greatly,while the glossiness of the paint films decreased slightly,from 48.6° to 47.0°.In alkaline media(pH 11),the volume of evolved H_2 of composite Al particles was only 3.5 mL,whereas that of raw Al was 83.5 mL.The glossiness of paint films containing composite Al particles decreased by 1.66%after immersion in alkaline media for24 h,whereas that of raw Al decreased by 14.82%.Peel-off tests of the paint films showed that the composite particles moved slightly away from the paint films.In contrast,the raw Al particles were seriously desquamated,suggesting encapsulation of hybrid films can greatly improve the adhesive properties of Al particles in paint films.Pihui Pi Chao Liu Xiufang Wen Lianfu Zheng Shouping Xu Jiang Cheng 2015Particuology2015,13,2:5
3Preparation and characterization of porous titania-grafted poly(styrene-divinylbenzene)/maleic anhydride nanocomposite microspheres显示文摘Mesoporous titania-grafted poly(styrene-divinylbenzene)/maleic anhydride [P(St-DVB)/MA] nanocomposite microspheres were prepared by an open ring reaction method.The titania nanoparticles were first modified by attachment of amino groups to their surface to prevent particle aggregation,and to allow the nanoparticles to covalently bond the polymer microspheres,the surface of which was modified by attachment of MA functional groups to enable the polymer to retain their porous structures and to react with the amino groups on the surface of the titania particles.The porous nanocomposite microspheres were detected by FTIR,SEM,TEM,XRD and UV-Vis spectrophotometry.The results indicated that the nanocomposite microspheres were composed of nanosized titania uniformly distributed on the surface,and exhibited better UV absorbing property than pure polymer microspheres or unmodified titania.Furthermore,compared with pure porous polymer microspheres,the nanocomposite microspheres showed more efficient UV protection and slow release of Parsol-1789(a photo-reactive and cosmetic agent) held inside the porous network of the microspheres.Li Sen Wang Kuan Zhang ZhiRen Song ChunLian Cheng Jiang Yang ZhuoRu Wen XiuFang Pi PiHui 2010Science China Chemistry2010,53,3:3

5Morphologies and Superhydrophobicity of Hybrid Film Surfaces Based on Silica and Fluoropolymer显示文摘Fluoropolymer and different kinds of silica particles were used for controlling surface chemistry and morphology, respectively.A superhydrophobic surface originated from strawberry-like or quincunx-shaped composite silica particles was obtained.The dual size particles are obtained by utilizing the graft of different modified silica particles with epoxy functional group and amine functional group.This makes the surface of film form a composite interface to have irregular binary structure which plays an essential role in trapping air between the substrate surface and the liquid droplets to be necessary for high contact angle and low contact angle hysteresis.The maximum contact angle for water on the hybrid film is about 174±2°and the contact angle hysteresis is less than 2°.The surface morphologies,roughness and the wettability on the surface of films containing different structural silica particles were compared.It was shown that the hierarchical irregularly structure with a low roughness factor and high air-trapped ratio is indispensable for superhydrophobic surface. Although this structural surfaces based on composite silica particles play a vital role in governing the surface wettability,it is necessary to combine with a low surface energy to make the surface superhydrophobic.Ailan QU Xiufang WEN Pihui PI Jiang CHENG Zhuoru YANG 2008Journal of Materials Science & Technology2008,24,5:2
