Title:
POLYMER-BASED SEMICONDUCTOR FIBER AND PREPARATION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/051079
Kind Code:
A1
Abstract:
The present invention relates to a polymer-based semiconductor fiber and preparation and application thereof. The preparation method comprises: preparing a conjugated semiconductor polymer into a spinning solution for wet spinning; performing wet spinning, spinning filaments extruded from a spinneret first sequentially entering a first coagulating bath and a second coagulating bath for drying, collecting the dried fibers, and annealing the collected fibers to obtain a polymer-based semiconductor fiber. Both the surface and the interior of the fiber have a pore channel structure, and the fiber further has an orientation structure. The polymer-based semiconductor fiber has a breaking stress of 700 MPa, a conductivity of 1×10 -12Scm -1-13S cm -1, and a carrier mobility of 0.0001-100 cm 2 V -1 s -1. The polymer-based semiconductor fiber is made into a fiber organic electrochemical transistor device, so that the transconductance of the device is significantly improved, and the conversion efficiency of the modulation of a gate voltage (V G) to the modulation of a drain current (I D) flowing through the entire channel is significantly improved.
