Problems solved by technology

In addition, in the prior art, an adhesive layer is used to achieve a firm combination of the antistatic layer and the anti-glare layer. Among them, the material of the adhesive layer often also affects the performance of the functional layer of the optical film.
[0006] Therefore, it is necessary to propose a new optical plate with both anti-glare and anti-static functions, which can be produced through a simpler process, and can overcome the large thickness and poor performance of the known anti-static and anti-glare optical plates. good question

Abstract

The invention provides a multifunctional optical film and a composite thereof, as well as a multifunctional optical plate and a manufacturing method thereof. The composite of the multifunctional optical film comprises optical resin and polyacetylene high-molecular conducting materials, wherein the polyacetylene high-molecular conducting materials account for 0.1-30wt% of the composite. The multifunctional optical film with antistatic and anti-dazzle functions is prepared by extruding the composite of the multifunctional optical film and then imprinting the composite of the multifunctional optical film through a micro-mist surface rolling wheel with the surface roughness of 0.01-1 micrometer. According to the invention, the multifunctional optical film is applied to the multifunctional optical plate, so that the market requirements for lightening and thinning are met by effectively reducing the thickness of the optical plate to a certain degree, and the problem that an antistatic layer and an anti-dazzle layer influence the property of the optical plate by being combined through the adhesion of an adhesive in the prior art is solved.
