Examples
Embodiment 1
[0048] 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
[0050] 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
[0052] 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
