Abstract

The invention provides a polyarylether sulfone copolymer with a main chain containing a platinum aromatic alkyne group and a preparation method of the polyarylether sulfone copolymer, and belongs to the field of high polymer materials. The preparation method comprises the following steps: carrying out nucleophilic polycondensation on a platinum-aromatic alkyne difluorobenzene sulfone monomer, aromatic organic bisphenol and 4, 4-difluorodiphenyl sulfone to obtain the soluble polyarylether sulfone copolymer with the main chain containing platinum aromatic alkyne. A polymer optical limiting material is prepared by introducing the platinum aromatic alkyne into a main chain structure of polyarylether, so that the application of the platinum aromatic alkyne is separated from a single solution system, a polymer solid optical limiting element with excellent thermal stability and mechanical performance is constructed, and the element has excellent third-order nonlinear optical effect and optical limiting performance. The prepared platinum-containing aromatic alkyne polyarylether sulfone film keeps good mechanical performance and optical limiting performance. The prepared polyarylether sulfone with the main chain containing the platinum aromatic alkyne structure can be applied to the fields of laser protection, nonlinear optics, fluorescence detection and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyaryl ether sulfone copolymer whose main chain contains a platinum aryl alkyne group and a preparation method thereof. Background technique [0002] In the late 1980s, laser technology began to develop rapidly and was used in various fields such as medicine, scientific research, military affairs, etc., and more and more appeared in people's daily life. But what follows is the damage of laser to various optical instruments and human eyes, especially the green light with a wavelength of 532nm is the most harmful to the retina. With the increase of various types of high-energy and high-power laser devices, laser protection is also becoming more It has been paid more and more attention by researchers at home and abroad. The optical clipping effect means that the medium has a high transmittance at low input light intensity, and the output light intensity in...
