An amino silicone oil-modified elastomer material includes Component A and Component R. Component A includes isocyanate prepolymer obtained through reaction of polyol and isocyanate, and the isocyanate prepolymer has a NCO content of 22-30%; Component R includes the following components in parts by weight: 45-60 parts of polyether amine, 1-6 parts of liquid amine chain extender, 1-10 parts of polysulfide rubber, 2-8 parts of nano silica, and 3-8 parts of amino silicone oil. The elastomer material of the invention ensures the elasticity of the polymer while improving mechanical properties. Moreover, it can improve elongation, wear resistance and water resistance of the polyurea material.

Cross-linked sol-gel like materials and cross-linked aerogels, as well as methods for making such cross-linked sol-gel like materials and cross-linked aerogels are described.

The present invention relates to a hybrid aerogel obtained by reacting an aromatic or aliphatic isocyanate compound and silanol moieties on a surface of a clay in a presence of a solvent. Hybrid aerogels according to the present invention provide high thermal insulation material, while good mechanical properties and performance is maintained.

A cover window includes a first layer having a first modulus, a second layer disposed on the first layer and having a second modulus smaller than the first modulus, and a third layer disposed on the second layer and having a third modulus equal to or larger than the first modulus, and in which the third layer includes a nanoparticle-polyurethane complex in which polyurethane is bonded with nanoparticles by a covalent bond. Therefore, the cover window of the present disclosure provides effects that the folding and rolling are possible with excellent surface characteristic and the restorability against the pressing and excellent optical property. A flexible display device may include the cover window.
