Abstract
The invention relates to a method for preparing a resin film layer with ultralow roughness, in which a liquid phase surface is used as a template. With the liquid phase surface as the template, resin is covered on the surface of the template, and the resin film layer with ultralow roughness can be copied by the cured resin. The resin film layer with ultralow roughness, prepared in the invention, can be applied to such fields as marine fouling, drag reduction, etc.
Description
Technical field
The present invention relates to a kind of is template using " liquid phase " surface, preparation has the side of the resin film layer of ultralow roughness
Method.
Background technology
Surface roughness is one of key factor of impact material property, also can affect some performances on surface.For example, table
Surface roughness can strengthen the apparent wettability on surface, in addition, the presence of surface roughness can affect between surface attachments and surface
Active force etc..The preparation therefore with special roughness surface is most important with application for the exploitation of functional material.
Low surface roughness surface is with a wide range of applications in actual industrial.It is experimentally confirmed that low coarse low surface
Affixing probability and the adhesive force of material surface antibacterial can be significantly reduced, this is opening of new anti-marine biofouling attachment material
Send out and foundation is provided.In addition, low roughness surface can significantly reduce the resistance of drop and its surface, can be applicable to draft reduction material
Exploitation.The method being presently used for reducing solid metal surface roughness is a lot, and conventional method includes mechanical polishing, electrochemistry
Polishing etc..But for organic polymer layers, the resin film layer especially commonly used in industry, its low roughness surface construction method is very
Few.
