The marvelous self-cleaning properties of lotus leaves and their superhydrophobic nature inspire the researchers to mimic such functionalities on cotton fabrics. The present work aimed to prepare and characterize true non-sticky superhydrophobic properties on cotton samples. The required combination of micro and nanostructure roughness was achieved by depositing the silica nanoparticles (SiNPs) on cotton surfaces by dip-coating method. To enhance adhesion and durability of silica particles with cotton, SiNPs were functionalized with 3-Aminopropyltriethoxysilane (APTES) before deposition. The surface energy of SiNPs coated cotton samples was lowered by functionalizing with 1H, 1H, 2H, 2H-Perfluorooctyltriethoxysilane (PFOTS). The morphology, surface chemistry and wettability characterizations of prepared samples were performed by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDX) and contact angle measurement system (goniometer) respectively. SEM micrographs revealed the nice decoration of SiNPs (having particles size range 90-150 nm) on the cotton fibers leaving to the hierarchical roughness. The EDX analysis confirmed the coatings of SiNPs and PFOTS. Contact angle measurements exhibited the superhydrophobic nature of prepared surfaces by static water contact angle of 157±2° and sliding angle of less than 5. The functionalized SiNPs/PFOTS cotton fabrics can effectively be used for self-cleaning applications.

“…It is well known that a combination of low-surface-energy materials and a special surface structure with high roughness are required to construct a superhydrophobic surface [6][7][8][9]. The construction of hierarchical structures with high surface roughness has been proven to be vital in generating the superhydrophobicity of a surface [10][11][12][13][14][15][16][17]. Many methods have been developed to fabricate artificial superhydrophobic surfaces, such as plasma etching [11], electrochemical deposition [12,13], chemical vapor deposition [14], electrospun [15], and layer-by-layer assembly [17].…”

Facile fabrication of superhydrophobic raspberry‐like SIO₂/polystyrene composite particles

A facile and novel strategy was reported on the fabrication of raspberry‐like SiO2/polystyrene (SiO2/PS) composite particles by emulsion polymerization in the presence of vinyl‐functionalized silica (vinyl‐SiO2) particles, which were prepared via a one‐step sol–gel process using vinyltriethoxysilane as the precursor. The submicron vinyl‐SiO2 particles were used as the core, and nanosized PS particles were then adsorbed onto the vinyl‐SiO2 particles to form raspberry‐like composite particles during the polymerization process. The composition, morphology, and structure of the vinyl‐SiO2 particles and the SiO2/PS hybrid particles were characterized by thermogravimetric analysis, nuclear magnetic resonance, Fourier transform infrared spectroscopy, transmission electron microscopy, and scanning electron microscopy. Superhydrophobic surface can be constructed by directly depositing the raspberry‐like SiO2/PS composite particles on glass substrate, and the water contact angle can be adjusted by the styrene/SiO2 weight ratio. In addition, the superhydrophobic film possessed a strong adhesive force to pin water droplet on the surface even when the film was turned upside down. POLYM.
