Embodiment 1

[0022] Heat 20g of sulfur to 185°C, heat to dissolve, add 20g of limonene, stir evenly, react at 185°C for 2 hours, then pour it on a glass plate to cool, or pour it directly into a mold for molding.

Embodiment 2

[0024] Excess limonene was reacted with sulfur according to Example 1 to obtain a vulcanized oligomer containing double bonds. Dissolve 3 g of the oligomer and 0.2 g of mercapto polysilsesquioxane (POSS-SH) in toluene and add light Initiator I907, after mixing evenly, irradiated with 365nm ultraviolet light, reacted for 12 hours, and carried out photocrosslinking. The photo-crosslinking process can be carried out directly in the mold with the inherent shape in conjunction with the template to complete the molding process of the lens.

Abstract

The invention discloses design synthesis of a polymer material with high infrared transmittance and preparation and processing thereof as an organic infrared film lens. Multiple polymer materials withhigh infrared transmittance are designed and synthesized according to the chemical group infrared absorption rule. The polymer infrared lens material is mainly prepared from the following series: diene (polyene) molecular sulfide polymers, inorganic hybrid materials and the like. The organic polymer material with high infrared transmittance can be used for manufacturing organic infrared film lenses, can be used for preparing a Fresnel lens or an organic infrared film lens with a superlens structure, and is used in lens components of thermal infrared imagers. The polymer infrared lens materialhas the beneficial effects that the synthesizing method is simple, raw materials are easily available, and cost is relatively low; the process for processing a film lens is simple and quick, can be used for preparing organic infrared film lenses and optical devices in large scale, and has an important application value in the fields of thermal infrared imagers and other researches and application.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of chemical materials, and in particular relates to the design and synthesis of polymer materials with high infrared transmittance. Background technique [0002] At present, precious semiconductor materials such as germanium single crystal and zinc selenide are mostly used in infrared lens materials, and the processing technology is complicated, the cost is high, and the yield rate is low, resulting in the price of infrared lenses is relatively expensive. According to the infrared absorption characteristics of organic functional groups, this patent designs and synthesizes polymer materials with high infrared transmittance, and uses methods such as photolithography, nanoimprinting, and step-flash imprinting to prepare Fresnel Organic infrared thin film lens with lens or metalens structure. Compared with the commonly used infrared lens materials such as germanium single crystal ...
