纳米二氧化硅

Abstract(#br)Two nanosilica A-300/zirconia (SZ) composites at zirconia content C ZrO 2 = 5 and 20\u003cce:hsp sp=\"0.25\"/\u003ewt.% were synthesized using a wet impregnation method with zirconium acetylacetonate as a precursor. The specific surface area of SZ is larger than that of A-300 because zirconia is composed of nanoparticles (crystallites of 4\u003cce:hsp sp=\"0.25\"/\u003enm in average size at C ZrO 2 = 20 wt . % ) smaller than those of the initial silica ( d av \u003cce:hsp sp=\"0.25\"/\u003e≈\u003cce:hsp sp=\"0.25\"/\u003e11\u003cce:hsp sp=\"0.25\"/\u003enm).

文摘本研究是通过喷涂聚二甲基硅氧烷( PDMS )与无机粒子的混合物，制备具有化学稳定疏水超疏水表面涂层的不同纸基材料。该方法易于实现，重现性好，需要廉价的起始原料。通过涂布应用选择( i )原纸( UC )、( ii )光泽涂布纸( GC )和( iii )哑光涂布纸( MC )表面的非彩色和有色型进行表面改性。水基油墨( WB )和溶剂基油墨( SB )配方均用于基材表面的染色。对涂布纸基材表面润湿性、光学和物理性能的研究表明，所提出的涂布应用方法是一种很有前景的用于包装的漆剂替代品。
