This invention mainly provides a mechanochromic polyester polyol, its preparation method, and its uses. The mechanochromic polyester polyol is prepared by esterification and polycondensation reactions of raw materials comprising 100 moles of a diacid / anhydride, 110-400 moles of a polyol, and 5-30 moles of a trihydroxyrhodamine derivative. The polyester polyol prepared by this invention contains mechanosensitive groups, aromatic rings, and a bialicyclic structure. The resulting polyurethane material exhibits excellent mechanochromic properties and high wear resistance.

The application discloses a kind of X-ray irradiation discoloration recovery test methods and application of feldspar crystal, it is related to radiation detection and irradiation metrology technical field.Natural colorless transparent feldspar or natural light color transparent feldspar is irradiated with different X-ray radiation dose, its color changes from colorless transparent or light color transparent to gray, and the gray scale is related to irradiation dose;After the color of the feldspar is changed, it is treated at different temperatures, or irradiated with visible light LED, to seek the best recovery parameters to restore its color to the original color.The method of the application can evaluate the discoloration performance of feldspar crystal and seek its best recovery parameters.The discoloration effect of natural colorless or light color transparent feldspar is obvious, easy to observe with naked eye, and the gray scale is related to the irradiation dose, which can also meet the needs of "transparent observation and light protection" in radiation protection scenarios.

This invention discloses a photochromic material incorporating a HOF (Hormone-Organic-Flatform) framework, its preparation method, and its applications. Belonging to the field of organic solid-state photochromic materials technology, it utilizes a host-guest eutectic method to load photochromic molecules onto the HOF framework material. This invention also discloses the photochromic material prepared by the above method, and its applications in information storage encryption and anti-counterfeiting. While achieving photochromism, the host-guest eutectic method exhibits a faster photoresponse rate and better photochromic performance compared to physical adsorption methods, showing greater potential in anti-counterfeiting and excellent information storage encryption capabilities.

Embodiments of the present invention relate to a curable transparent resin composition and various articles derived therefrom. The curable transparent resin composition comprises: (A) a fluororesin containing one or more carboxyl groups; and (B) an epoxy resin. This curable transparent resin composition exhibits excellent dry film properties, heat resistance, transparency, adhesion, and discoloration resistance through the combination of the two components, and thus enables the formation of a thin film having an excellent adhesion and discoloration resistance while having a light transmittance at a similar level to that of a silicone resin composition that is commonly used for display applications. Thus, the curable transparent resin composition of the present invention can be used not only as a display component requiring excellent light transmittance, but also as a variety of applications such as an LED sealing material, a glass adhesive, a dry film, or a chip bonding material, which require excellent adhesion and discoloration resistance.

The present application relates to the technical field of textile, and particularly refers to a multi-comb illusion jacquard fabric and a weaving method thereof. The fabric is a single-sided fabric, which is woven by a single needle bed jacquard machine and includes four layers of weaving structures. The weaving structures include, in sequence, a face yarn layer with a planar structure, a ground comb jacquard layer connected to the face yarn layer and including longitudinally convex strip parts and longitudinally concave strip parts which are spaced apart along the lateral direction of the fabric, an illusion jacquard layer connected to the ground comb jacquard layer and including a plurality of float thread structures, each of which extends along the longitudinal direction of the fabric and the plurality of float thread structures are distributed on the left side or the right side of the longitudinally convex strip parts of the ground comb jacquard layer, and a presser layer connected to the illusion jacquard layer and used for fixing the float thread structures. The present application first proposes a single-layer color-changing mesh fabric, which has excellent light and thin breathable properties and a stable fabric structure, and is a once innovation of combining warp-knitted mesh fabric with color-changing and jacquard, and the process is environmentally friendly.
