Superhydrophobic surfaces prepared from water glass and non-fluorinated alkylsilane on cotton substrates

Large-area fabrication of superhydrophobic surfaces for practical applications: an overview

“…Li et al [45] used sodium silicate, a cheap and commonly used industrial raw material, as the precursor to prepare a silica sol by acid-catalyzed hydrolysis and condensation. After dip-coating the silica sol onto cotton surfaces, the surfaces were modified with hexadecyltrimethoxysilane to obtain a thin layer through self-assembly.…”

Biological Applications of Biomimetic Superhydrophobic Surfaces

“…对于表面能较低的材料而言, 在其表面构筑微 纳米粗糙结构是实现超疏水性能的关键环节. 目前, 已 经报道了许多比较成熟的制备技术, 如电化学沉积 法 [16,17] 、等离子体和激光刻蚀法 [18,19] 、交替沉积法 [20,21] 、 电纺丝法 [22,23] 、模板法 [24,25] 、溶胶-凝胶法 [26] 等. 生物医用材料在当今医学领域占有极其重要的地 位, 如用于组织修复…”

Superhydrophobic cotton fabrics prepared by sol–gel coating of TiO2and surface hydrophobization

“…Among others, superhydrophobic textiles have been successfully obtained by a number of different approaches [9][10][11][12][13][14][15][16]. For example, Gao and McCarthy, according to a 1945 patent, grafted a silicone coating to a microfiber polyester fabric to render the fabric superhydrophobic [9], but the microfiber polyester fabric (with a single fiber as small as 2-5 µm) must be tightly woven, and this approach may not be suited to cotton textiles.…”

“…Michielsen and Lee [16] used mechanical and chemical surface modifications with further grafting of 1H,1H-perfluorooctylamine or octadecylamine to poly(acrylic acid) chains, which was previously grafted onto a nylon 6,6 woven fabric surface, to prepare artificial superhydrophobic surfaces. Li et al [15] prepared superhydrophobic surfaces from water glass and nonfluorinated alkylsilane on cotton substrates.…”
