Optical lens, molecular thin film coated on such optical lens, and manufacturing method of such molecular thin film

Abstract

The invention relates to the technical field of a molecular thin film and a manufacturing method of the molecular thin film, and discloses a molecular thin film coated on an optical lens. The molecular thin film contains the n-octadecyl trichlorosilane and an antibacterial drug, wherein the weight ratio of the antibacterial drug to the n-octadecyl trichlorosilane is 3-13. The invention further discloses a manufacturing method of the molecular thin film, the method comprises the following steps of: a preposed step of preparing a matrix, the n-octadecyl trichlorosilane and an antibacterial drug in advance; a cleaning step of cleaning the oil and the pollutant on the surface of the matrix; and a soaking step of soaking the matrix in a mixture to form a molecular thin film on the surface of the matrix, wherein the mixture is composed of the n-octadecyl trichlorosilane and the antibacterial drug. The molecular thin film not only can resist pollution and avoid adhering of outside dust and smudginess, but also can effectively resist the pollution of normal bacterial flora and fungus flora in the environment, thereby improving the light transmission and prolonging the service life of the optical lens.

Description

technical field [0001] The invention relates to a molecular thin film and a manufacturing method thereof, in particular to a molecular thin film coated on an optical lens and a manufacturing method thereof. Background technique [0002] In an era where visual effects are increasingly valued, the reliability and aesthetic requirements of industrially produced display elements during use will become more and more important. [0003] Generally, the surface of optical lenses has anti-wear properties, but there are still two disadvantages as follows: [0004] 1. Poor anti-fouling property: Since particles and moisture are easily attached to the surface of the lens in the atmospheric environment, the wear and light transmission effect will be deteriorated. Therefore, how to modify the surface of the molecular film on the hard coating to make the It reduces the slow damage of the environment to the surface of the coating, and does not damage its own performance, which is an urgent...

Problems solved by technology

[0004] 1. Poor anti-fouling property: Since particles and moisture are easily attached to the surface of the lens in the atmospheric environment, the wear and light transmission effect will be deteriorated. Therefore, how to modify the surface of the molecular film on the hard coating to make the It reduces the slow damage of the environment to the surface of the coating, and does not damage its own performance, which is an urgent problem for products to be solved

[0005] 2. Poor antibacterial properties: In addition to the advantages of good anti-fouling properties, the surface of the lens is also one of the key points. The antibacterial effect of the surface of the lens is related to the attachment and growth of fungi on the surface of the lens. When the antibacterial effect of the surface is not good When the fungus is easy to attach to the surface and grow, it will affect the performance of the product

[0007] However, although pentadecyl mercaptan (HDT) and n-octadecyl trichlorosilane (OTS) of the prior art can convert SiO 2 Glass or MgF 2 surface modification of the glass so that the SiO 2 Glass or MgF 2 The contact angle of the glass is increased from 66 or 19.7 to 111.4 to improve its stain resistance, but the antibacterial effect of the optical lens cannot be improved at the same time; therefore, the modification methods of the prior art still have deficiencies, and further improvement is necessary to promote industrial production
