Abstract

The invention discloses a method for preparing electrostatic spraying polyacetylene particles and belongs to the field of electrostatic spinning. According to the method, an electrostatic spraying technology is utilized, a helix substituted acetylene polymer polyphenylene (PPA) and helix substituted propyne polymers (PFA (perfluoroalkoxy), PSA (polysulfonamide), PCFM, PX (para xylene)) are adoptedas representatives, and polyacetylene particles with uniform particle size distribution can be prepared by controlling the concentration of a polymer electrostatic spraying solution and adjusting related electrostatic spraying parameters. In order to further enrich the types and preparation methods of the polyacetylene particles, a copolymer of two monomers (FA / PA) copolymer and a comixture of polymers (PFA / PPA) of the monomers are further adopted for electrostatic spraying, by adjusting a copolymer composition ratio and a comixture composition ratio, structures, morphologies and chiral properties of particles can be adjusted, and multiple types of morphology adjustable polymer particles can be prepared. The method is simple to operate, uniform in particle size distribution, good in dispersibility and good in applicability.

Description

technical field

[0001] The invention relates to the preparation of polyyne particles and the regulation of particle morphology, which is a method for preparing a series of polyyne particles with specific shapes by using electrostatic spray technology, and belongs to the field of electrostatic spinning. Background technique

[0002] Chirality is a common feature in nature and plays an indispensable role in the generation and evolution of life. The so-called chirality refers to the characteristic that an object and its mirror image cannot overlap. The so-called chiral molecule refers to the molecule whose configuration and its mirror image cannot overlap. In recent years, chirality and related research topics (such as the synthesis of chiral drugs, chiral separation, chiral materials, etc.) have attracted more and more attention. Among them, chiral particles have the advantages of large specific surface area, strong dispersion ability, good processing performance, controllab...
