Embodiment 1

[0045] Placing PTFE fibers in SiCl 4 After being in the atmosphere for 1 hour, the temperature was raised to 110° C. and maintained for 1 hour, and then cooled to 60° C., and sprayed with water to obtain silica-modified polytetrafluoroethylene fibers.

Embodiment 2

[0047] Put alkali-free glass fiber in Ti(OEt) 4 Add concentrated ammonia water to hydrolyze and stand still in the water mixing system under stirring to obtain the alkali-free glass fiber modified by titanium dioxide.

Embodiment 3

[0049] Triethyl phosphate and tetraethyl orthosilicate (1:100 mass ratio) were mixed and added to water and concentrated ammonia water to static gel for 12 hours, and then the gel was used to obtain phosphoric acid-modified silica fibers by electrospinning or spinning technology

Abstract

The invention relates to a multilayer cross-linking organic doped fluoric ion film with reinforced fiber and preparation method thereof, belonging to the field of functional high molecule composite material, which is composed of a fluoric ion exchange film and reinforced fiber. The ion exchange film prepared by this invention has high proton conductivity, high mechanical performance, good chemical and mechanical stability, which can effectively prevent penetration of hydrogen and methanol.

Description

technical field [0001] The invention belongs to the field of functional polymer composite materials, and relates to a fiber-reinforced multilayer fluorine-containing ion-exchange membrane, in particular to a fiber-reinforced fluorine-containing ion-exchange membrane and a preparation method thereof. Background technique [0002] Proton exchange membrane fuel cell is a power generation device that directly converts chemical energy into electrical energy by electrochemical means, and is considered to be the preferred clean and efficient power generation technology in the 21st century. Proton exchange membrane (proton exchange membrane, PEM) is the key material of proton exchange membrane fuel cell (proton exchange membrane fuel cell, PEMFC). [0003] Although the current perfluorosulfonic acid proton exchange membrane has been used for many years, there are still some shortcomings that cannot meet the requirements of commercialization, such as low proton conductivity at high t...
