Problems solved by technology

At present, the elastic body blood vessel model needs to work under the condition of constant water circulation, which brings great inconvenience to practical application
However, under anhydrous conditions, the surface frictional resistance of elastomers is too great to use
At present, there is still a lack of elastomeric vascular model products that can work in an anhydrous environment and can directly observe the position and movement of implanted medical devices in the vascular model without the need for other imaging equipment, that is, the surface is super lubricated Elastomer products with high transparency

Abstract

The invention provides a highly transparent elastomer with a super-lubricating surface and a preparing method and application thereof. The elastomer comprises an elastomer base material and a lubricating coating which is attached to the surface of the elastomer base material; the lubricating coating comprises fluorinated polymer brushes and fluorinated polyether oil which infiltrates gaps betweenthe fluorinated polymer brushes. The fluorinated polymer brushes and the fluorinated polyether oil which infiltrates the gaps between the fluorinated polymer brushes complement each other, synergize and act together to make the surface of the elastomer have the stable and long-acting advantages of being super-lubricating and highly transparent.

Description

technical field [0001] The invention belongs to the technical field of elastomers, and in particular relates to an elastomer and its preparation method and application, in particular to an elastomer with super lubricating surface and high transparency, its preparation method and application. Background technique [0002] Elastomers generally refer to materials that can return to their original shape after the external force is removed, including thermosetting elastomers and thermoplastic elastomers. Silicone, latex, rubber, polyurethane, etc. are common elastomers. Elastomers are used in all aspects of life, and can be modified in different ways according to different needs, such as several surface-modified elastomers involved in the following patents. [0003] CN103405335A discloses a surface-modified rubber plug and a preparation method thereof. The rubber plug includes a rubber plug body and a modification layer on the surface of the body modified by PVDC emulsion. That ...
