Embodiment 1
[0033] An anti-fingerprint antibacterial glass and a preparation method thereof, comprising an original glass sheet and an anti-fingerprint antibacterial film covering the upper surface of the original glass sheet. 8% permanent acrylic resin, 60% toluene, 25% dichloromethane, 7% ethanol dispersion of 0.5wt% fluorinated silver-loaded carbon nanohorn.
[0034] A preparation method of fluorinated silver-loaded carbon nanohorn ethanol dispersion comprises the following steps:
[0035] 1) Carboxylation modification of single-walled carbon nanohorns (SWNHs), disperse 100 mg of SWNHs into 150 ml of nitric acid solution and reflux at 120 °C for 24 h to obtain carboxylated SWNHs, wash with deionized water several times and then vacuum dry at 90 °C .
[0036] 2) Disperse 0.2g of carboxylated carbon nanohorns in 40ml of methanol solution and mix evenly, add 2ml of perfluorooctyltrimethylsilane, stir at room temperature for 16h, heat to 120°C and continue stirring for 1h to obtain fluori...
