Abstract: An optical construction includes a reflective polarizer and an optical film. The optical film includes a matrix and a plurality of first particles dispersed in the matrix. Each of the matrix and the plurality of first particles includes a silicone polyoxamide and an acrylate polymer. For substantially normally incident light and for at least a first wavelength in a first wavelength range, the reflective polarizer reflects about 60% for a first polarization state and transmits about 40% for an orthogonal second polarization state. For at least a second wavelength in a second wavelength range, each of the reflective polarizer and the optical film transmits about 60% of an incident light for each of the first and second polarization states. For at least the first wavelength, optical film has an optical haze and a depolarization ratio. A ratio of the depolarization ratio to the optical haze is less than 0.1.

Abstract: Phase separated articles that include a matrix phase including an acrylate copolymer; and a silicone elastomer phase stably dispersed in the matrix phase are described. The matrix phase may be derived from precursors comprising from 60 to 95 parts by weight of an alkyl acrylate having an alkyl group having 1 to 14 carbon atoms. Methods of forming phase separated articles, and articles including phase separated articles are also described.

Abstract: Provided is a method of forming a fibrin hydrogel composition, the method including providing a fibrin hydrogel or precursor thereof, comprising fibrin hydrogel forming salt. The fibrin hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrin hydrogel. The method further includes combining the fibrin hydrogel with a carrier material. The concentration of the carrier material typically ranges from 0.1 to about 50 wt.-%. The method further includes reducing the salt concentration below the threshold concentration to form a fibrin hydrogel.

Abstract: Provided is a method of forming a fibrinogen hydrogel composition, the method including providing a fibrinogen hydrogel or precursor thereof, comprising fibrinogen hydrogel forming salt. The fibrinogen hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrinogen hydrogel. The method further includes denaturing the fibrinogen hydrogel such as by heating. The method optionally further includes combining the fibrinogen hydrogel with a carrier material. When present, the concentration of the carrier material typically ranges from 0.1 to about 50 wt.-%. The method further includes reducing the salt concentration below the threshold concentration to form a fibrinogen hydrogel.
