摘要:先前已经制备了含有磷钨酸(pwa)的溶胶－凝胶衍生的有机－无机杂化体,以获得质子传导膜.然而,为了获得更高的质子传导率,Pwa的泄漏是一个严重的问题.在这项研究中,通过溶胶-凝胶法制备了带有磺酸基团的聚电解质膜.在阻抗分析仪上于80oc / 95%rh下进行质子电导率测量.功能化的聚电解质膜表现出质子电导率σ〜0.9(s / Cm),远高于先前报道的含pwa的杂化体.尽管无论使用何种催化剂,杂化物均表现出相当高的质子传导性,但在较低的相对湿度下,其强烈依赖于催化剂.在这项研究中准备的杂种中,由于离子簇溶胀形成的质子传输通道,即使在低湿度下,用hcl合成的膜仍具有出色的质子传导性能.通过测量离子交换容量,吸水率,溶胀率,傅立叶变换红外光谱,原子力显微镜和热重分析,可以证实这一事实.©2012 Wiley Periodicals,Inc.

摘要:The invention discloses and claims a new class of chemical compositions with ideal sunscreen properties. The chemical composition comprises spherical particles between 200 nm and 10 microns in diameter prepared by an emulsion polymerization of tetraalkoxysilanes or organotrialkoxysilanes or organobridged trialkoxysilanes with a dye monomer bearing two or more alkoxysilyl groups attached to the bridging chromophore. The resulting spheres absorb ultraviolet light. The dye can be any organic chromophore capable of receiving multiple trialkoxysilyl groups resulting in multipoint covalent attachment that precludes leaching of the dye from the spheres. The formic acid-toluene-monomer emulsion polymerization allows for large-scale (>100 gram) synthesis of monodisperse particles under acidic, non-aqueous conditions without surfactants. The particles less than 1 micron in diameter are smooth as talc to the touch and will provide a smooth formulation for sunscreen creams or lotions.
