This invention provides an adhesive polarizing film capable of suppressing the increase in surface resistivity of an adhesive layer under high-temperature conditions. According to the invention, an adhesive polarizing film is provided, which is composed of an adhesive layer and a polarizing film laminated together, wherein the adhesive layer is formed of an adhesive composition containing an adhesive and a conductive polymer, and the storage modulus (G') of the adhesive layer at 80°C is 20–1000 kPa.

This invention belongs to the field of hydrogel preparation. It discloses a mid-internal phase Pickering emulsion gel, its preparation method, and its applications. The gel comprises glycyrrhizic acid, a cationic compound, an oil phase, and water. The glycyrrhizic acid in the emulsion gel is 0.7-1.5 wt% by weight (based on available glycyrrhizic acid); the cationic compound is 0.1-0.5 wt% by weight, and is selected from at least one of lysozyme, polylysine, zinc chloride, calcium chloride, or magnesium chloride; the oil phase has a volume fraction of 30%-70%. This invention achieves efficient gelation under mid-internal phase conditions through electrostatic bridging of low-concentration glycyrrhizic acid and trace amounts of cations, overcoming the dependence of traditional techniques on high-concentration emulsifiers, composite systems, or high oil phases.

The invention discloses hydrogel with a spontaneous negative swelling behavior as well as a preparation method and application of the hydrogel, and belongs to the technical field of biological materials. The hydrogel disclosed by the invention is prepared from sodium alginate (SA) and recombinant human-like collagen (RHLC) with a specific Gly-Xaa-Yaa repetitive sequence through an internal ion cross-linking method; the hydrogel can spontaneously generate negative swelling in a water-based environment without any external stimulation, the maximum weight reduction rate exceeds 26%, and network structure densification and self-enhancement of mechanical properties are realized in the process; the hydrogel solves the problems that the traditional hydrogel is easy to swell and unstable in mechanical property, and has extremely high application value in the fields of intelligent wound dressings, controllable drug release, cosmetics (lifting efficacy eye masks or facial masks), flexible sensors and the like.

The invention relates to the technical field of functional polymer materials, in particular to a wide-temperature-range sound insulation intermediate film and a preparation method thereof. The middle film comprises at least one functional layer A and at least one functional layer B which are stacked; the tan delta peak temperature Ta of the functional layer A satisfies 30 DEG C < = Ta < = 50 DEG C, and the Mw / Mn of the resin constituting the functional layer A is 1.8-2.5; the content of the plasticizer in the functional layer A is 35-45 phr; the tan delta peak temperature Tb of the functional layer B is greater than or equal to-10 DEG C and less than or equal to 10 DEG C, and the Mw / Mn of the resin forming the functional layer B is 4.5-6.5; and the content of the plasticizer in the functional layer B is 55-65 phr. Through core differential molecular design, the functional layer A and the functional layer B respectively have specific dynamic viscoelastic characteristics, molecular weight distribution and plasticizer content. After the two components are compounded, the damping peak is between-10 DEG C and 50 DEG C, so that continuous and effective coverage and synergy are realized.
