玻璃表面含氟疏水自清洁涂层的制备及耐磨性能OA

To enhance the self-cleaning and wear resistance properties of fluorine-containing hydrophobic coatings,a self-cleaning coating solution was prepared by in-situ polymerization of 1,2-cyclohexanedione,trifluoromethylsilane,and BF3·Et2 O in perfluoro-tert-butanol.The solution was sprayed onto glass substrates to form films,which were then treated at different curing temperatures and times to obtain a series of superhydrophobic self-cleaning coatings with varying curing processes.The study focused on the effects of curing temperature and time on the transmittance,contact angle,and wear resistance of the hydrophobic coatings.The results showed that as the curing temperature increased from room temperature to 210℃,the transmittance,haze,and contact angle of the coatings initially increased and then decreased.Similarly,with increasing curing time,the transmittance,haze,and contact angle first decreased and then increased.When the coating was cured at 150℃for 30 min,the transmittance and haze were 93.1%and 0.6%,respectively,and the contact angle reached as high as 119.5(°).The coating failed after 7000 cycles of friction testing.These findings indicate that the prepared fluorine-containing hydrophobic coatings exhibit excellent self-cleaning and wear resistance properties.
