Description

technical field [0001] The invention belongs to the technical field of nanomaterials, and in particular relates to an anti-fingerprint surface nano coating and a production method thereof. Background technique [0002] During the use of the touch screen, it is easy to be affected by fingerprints, which requires the touch screen to have an anti-fingerprint effect. The existing principles of anti-fingerprint coatings for touch screens mostly use the hydrophobic properties of coatings to achieve anti-fouling and anti-fingerprint effects, but on the other hand, the current common anti-fouling The tension is relatively large, so when sweat or stain droplets adhere, the contact angle is relatively small, and it is relatively easy to adhere, that is, the anti-fouling and anti-fingerprint effect is poor, so there is an urgent need in the market for a product with a small surface tension and a large contact angle when sweat adheres. , and finally a new type of high-efficiency coatin...
