Method for preparing polyacetylene electrospun nanofibers

Abstract

The invention discloses a method for preparing polyacetylene electrospun nanofibers, and belongs to the field of electrostatic spinning. An electrostatic spinning technique is applied to the method, the type and content of polyacetylene in spinning solutions are controlled, and accordingly, continuous polyacetylene nanofibers of which the diameter distribution is controllable to a certain degree can be obtained. To further improve the performance of the nanofibers, a conventional electrospun high polymer is selected and then blended with the polyacetylene to obtain the composite nanofibers with excellent mechanical properties. Experimental operations involved in the method are simple. The obtained polyacetylene nanofibers are flexible, have optical activity and can be curled, thereby having high applicability.

Background technique

[0002] Inspired by the helical structure of natural macromolecules, scientists turned their attention to the research of artificially synthesized helical polymers. With the development of polymer synthesis chemistry, many helical polymers with different properties and functions have been synthesized through molecular design, such as polyisocyanide, polymethacrylate, polyacetylene chloride, polysilane and polyacetylene, etc. . In recent years, with the development and utilization of new polymerization systems and catalysts, a large number of helical polymers, especially optically active helical substituted polyynes, have been successfully synthesized and widely...
