Synthesis of ladder-like phenyl polysilsesquioxane with fluorinated side chains and its use in silicon/polycaprolactone electrospun membranes with excellent anti-fouling, self-cleaning, and oil-water separation performances

Advanced polymer processing technologies for micro‐ and nanostructured surfaces: A review

“…[ 41 ] The fiber diameter and morphology will depend on the electrospinning processing parameters, such as temperature, relative humidity, flow rate, concentration, collection distance, and applied voltage. [ 42–44 ] The ability to produce electrospun fibers in different length scales in a convenient process makes it a promising technique for several potential applications requiring liquid repellency, for example, filter membranes, wound dressings, nano‐sensors, protective clothing, and biomedical scaffolds.

Recent progress in ladder-like polysilsesquioxane: synthesis and applications

“…105,107 Studies have also utilized catechol functional groups 104 for their hydrophilic properties and strong adhesion, as well as fluorine-containing chains to confer hydrophobic characteristics. 183 Consequently, LPSQ has found widespread use in selective permeation studies of ionic substances, with ionic functional groups introduced to facilitate interaction and selective permeation. 103 Phenyl groups are utilized to enhance structural ordering, 31 while the length of alkyl chains is optimized to improve LPSQ's processability.…”

“…[189][190][191][192] For certain applications, these coatings must also maintain optically transparency. 178,179 Additionally, they may require properties like water resistance, [193][194][195] oilrepellence, 196,197 flame retardancy, 89 antifouling, 183 and antibacterial capabilities. 186 Although POSS has been extensively explored as an additive in coating resins to enhance hardness, its utility is somewhat restricted because of its limited solubility, leading to aggregation when used at high concentrations.…”
