A novel approach to raspberry-like particles for superhydrophobic materials

Insights into the superhydrophobicity of metallic surfaces prepared by electrodeposition involving spontaneous adsorption of airborne hydrocarbons

“…On the basis of this principle, a number of strategies have been developed to fabricate artificial superhydrophobic surfaces through controlling both of surface chemical composition and surface morphological structures. For example, superhydrophobic cotton textiles by solution immersion of polymethylsilsesquioxane [14], superhydrophobic coatings of organic/inorganic composites by sol-gel processes [15], superhydrophobic rose-like mordenire zeolites by hydrothermal synthesis and surface modification with octyltrimethoxysilane [16], superhydrophobic polystyrene films by phase separation [17], superhydrophobic silica-spherecoated substrates by fluorination treatment and layer-by-layer deposition of poly(diallyldimethylammonium chloride)/sodium silicate multilayer films [18], superhydrophobic substrates with dual-sized raspberry-like polystyrene/silica particles by colloidal self-assembly and surface modification with dodecyltrichlorosilane [19], superhydrophobic metal surfaces by electrodeposition [20,21] or electrooxidation [22] deposition [23], superhydrophobic aluminum alloy substrates by chemical etching in the presence of lauric acid [24], and so on [25,26].…”

Facile fabrication of snowman-like Janus particles with asymmetric fluorescent properties via seeded emulsion polymerization

“…The size of P(St-DVB-AA) particles was slightly smaller than that of P(St-AA) particles due to the contraction of the cross-linked network [23]. In addition, carboxylic acid groups of AA were mostly located on the surface of microspheres due to their hydrophilic nature after the copolymerization of soap-free emulsions [43]. Figure 2 shows the FT-IR spectrum of P(St-DVB-AA) microspheres with 0.5 % degree of cross-linking.…”

Investigation of the effect of dual-size coatings on the hydrophobicity of cotton surface

“…SiO 2 particles are the most widely used coating materials due to their nontoxicity, availability, and easy handling. Although hydrophobicity can be achieved with single-layer, single-length scale features, successive deposition of particles of different sizes, using layer-by-layer techniques (LbL), can generate greater hydrophobicity and stability of the surfaces (Li et al 2009;Bravo et al 2007;Raza et al 2010;Su et al 2010;Xia et al 2008;Amigoni et al 2009;Xue et al 2010;Tsai and Lee 2007;Qian et al 2009;Liu and He 2009;Ji et al 2006;Liu et al 2008). LbL employs complementary interactions, such as electrostatic attraction or covalent bonding, and allows the thickness of the resulting layer to be controlled.…”
