Modification Method of Single Hydroxyl Functionalization of Fluorine Resin

Abstract

The invention discloses a modification method for single hydroxyl functionalization of fluorine-containing resin. The modification method comprises the following steps: Step 1: processing the fluorine-containing resin into a film with a certain thickness; Step 2: plasma-activating a surface of the fluorine-containing resin film; Step 3: using a reducing agent to reduce a complex oxygen-containingfunctional group on the surface of the fluorine-containing resin into a single hydroxyl. The fluorine-containing resin obtained by the method used in the invention has an excellent adhesive property;compared with a traditional way of activating the fluorine-containing resin with high-activity metal, the method has an advantage of simple and safe operation; the obtained hydroxyl-containing fluorine-containing resin can utilize the hydroxyl for further molecular designing to broaden an application field of materials.

Description

technical field

[0001] The invention relates to a material modification method, in particular to a modification method for performing single hydroxyl functionalization on fluorine-containing resins by using low-temperature plasma. Background technique

[0002] In the field of energetic material processing, fluorine-containing resin is often used for bonding energetic material particles, and is an important part of the bonding system. Only under its action, energetic material particles can maintain a certain geometric shape and a good shape. mechanical properties. The advantage of fluororesin lies in its relatively high density, excellent low temperature performance and physical and chemical stability. The commonly used fluororesin is F2314 (1:4 copolymer of vinylidene fluoride and chlorotrifluoroethylene).

[0003] Although fluorine-containing resins have many advantages, their disadvantages are also obvious. The most important point is that due to the high fluorine conten...
