“…The scratch depth increases to 40.33 µm, indicating the disruption of covalent bond between coating and glass surface. At the constant stress, the coated substrate undergoes crack’s propagation at shorter distance (Wang et al , 2019). The coated surface showed no adhesive failure ( L c 2 ) because its high covalent Si–O–Ti bond prevents the destruction of tensile stress on glass substrates.…”

Purpose This paper aims to design the nano-titanium dioxide (TiO2) coating system which has superhydrophilic property, self-cleaning mechanism and antifog property as well as strong adhesion on glass substrate. Design/methodology/approach Two hydrophilic materials have been used such as TiO2 nanoparticles as fillers and hydrophilic copolymer, Pluronic F-127 by using simple sol–gel approach. The prepared solution was applied onto glass through dip- and spray-coating techniques and then left for drying at ambient temperature. Findings The nano-TiO2 superhydrophilic coating has achieved the water contact angle of 4.9° ± 0.5°. The superhydrophilic coating showed great self-cleaning effect against concentrated syrup and methylene blue where thin layer of water washes the dirt contaminants away. The nano-TiO2 coating exhibits great antifog performance that maintains high transparency of around 89% when the coated glass is placed above hot-fog vapor for 10 min. The fog droplets were condensed into water film which allowed the transmission of light through the glass. The strong adhesion of coated glass shows no total failure at scratch profile when impacted with scratch load of 500, 800 and 1,200 mN. Research limitations/implications Findings will be useful in the development of self-cleaning superhydrophilic coating that is applicable on building glass and photovoltaic panel. Practical implications The developed nano-TiO2 coating is developed by the combination of hydrophilic organic copolymer–inorganic TiO2 network to achieve great superhydrophilic property, optimum self-cleaning ability and supreme antifog performance. Social implications The findings will be useful for residents in building glass window where the application will reduce dust accumulation and keep the glass clean for longer period. Originality/value The synthesis of nano-TiO2 superhydrophilic coating which can be sprayed on large glass panel and cured at ambient temperature.

The long-term fatigue performance of a glass fibre-reinforced thermoplastic pipe (RTP) is mainly determined by that of its glass fibre reinforcement layer. Glass fibre has an irregular network structure consisting of SiO 4 tetrahedrons. In this network structure, there exists numerous defects. Under cyclic loading, cracks are initiated at these defects and grow steadily and perhaps even disruptively, ultimately leading to the fracture of the glass fibre. The mean stress corresponding to the occurrence of disruptive crack propagation is referred to as the critical fatigue stress. When the mean cyclic load is smaller than the critical value, the growing cracks stop propagating when in contact with high-energy chemical bonds. When the mean cyclic load is larger than the critical value, the glass fibre is doomed to fracture. In the present study, a series of fatigue tests was performed on a RTP subjected to cyclic loadings of different mean stresses. The numbers of cycles to failure at different mean stresses obtained from the tests were then used to estimate the critical fatigue stress of the RTP. The mechanism underlying the fatigue failure was analysed using fatigue mechanics and chemical bond theories. Test Testing materialsGlass fibre strip: Glass fibre bundles were wetted via soaking in a batch solution and then baked dry in an oven. The pre-treated bundles were bonded with molten HDPE in a mould. The resulting composite material was rolled into strips. The glass fibre (2400 TEX) measured 0.6 mm in thickness and had a density of 1.3373 g cm −3 and vertical fracture stress of 300 MPa.
