Superhydrophilicity and durability of fluoropolymer-TiO 2 coatings

Preparation, thermostability, and hydrophobic properties ofTiO2/poly(dodecafluoroheptyl methacrylate) nanocomposites

“…The largest WCA of 120° ± 1° is obtained when the content of TiO 2 is 30 wt %. When the content of TiO 2 reaches below 30%, according to the previous researches, the improved hydrophobicity of the nanocomposite might be closely related to the increased surface roughness in the presence of TiO 2 and chemical crosslinking degrees caused by the reaction. However, at higher loading of TiO 2 (beyond 30%), the value of WCA of the composites is declined.…”

Fundamentals and Applications of Surface Wetting

“…For instance, the durability and stability of widely used self-cleaning fluoropolymer TiO 2 superhydrophilic coatings are greatly influenced by time of ultraviolet exposure, followed by the amount of the polymer in the composition used. 347 In applications related to waterenergy nexus, durable superhydrophilic surfaces play a major role in antibiofouling. Recently, such durable surfaces have been observed to increase the overall efficiency of oil−water separation.…”

Remediation of Fouling on Painted Steel Roofing via Solar Energy Assisted Photocatalytic Self‐Cleaning Technology: Recent Developments and Future Perspectives

“…[ 143 ] Accordingly, polysiloxanes and fluorocarbon polymers have been used as the primary component in the protective layer compositions. [ 143,144 ] The patent literature confirms the application of an additional protective layer in between the photocatalytic top layer and the underlying paint layer by using colloidal silica and 2‐[methoxy(olygoethylenoxy)propyl]heptamethyltrisiloxane as the organosilicon surfactant. [ 143 ] Similarly, silicates, silicone, or alkyl alkoxysilane‐based materials have been used in several other patents as the protective layer composition to enhance the service life of photocatalytic coatings via the minimization of photodegradation of internal paint components.…”
