Abstract: A polymeric hybrid material with photothermal properties is provided. The polymeric hybrid material containing polydopamine and particles of at least one of the polymers that are homogeneously dispersed and stable in a basic aqueous medium, where the surfaces of said polymer particles are coated with polydopamine, and the particles of polyurethane are in a sub-micron scale.

Abstract: A production method of boron carbide nano-sized particles and/or submicron particles includes the following sequential steps: obtention of a fluid mixture including elemental boron, glycerin and one or more carboxylic acid, wherein a molar ratio of glycerin to the one or more carboxylic acids is within a range between 10:1 and 10:7.5. Heating of the fluid mixture to obtain a first mid-product in a form of a gel including borate ester bonds. Solidification of the first mid-product by heating a reaction product to obtain a second mid-product in solid form. Sintering the second mid-product to obtain boron carbide in a form of particles.

Abstract: A polymeric composition containing at least one polymer and halloysite nanotubes is disclosed. At least a portion of the halloysite nanotubes is loaded with a phase change material and each of the loaded halloysite nanotubes contains at most one kind of phase change material. In addition, a preparation method and use of the polymeric composition are further provided.

Abstract: A photothermal composition configured to be used in air filter for destroying bioaerosol particles by converting light energy emitted from a light source into heat energy including a photothermal agent is provided. The present invention also concerns an air filter for collecting the bioaerosol particles in an air flow and destroying said bioaerosol particles deposited thereon, including a photothermal agent which converts light energy emitted from a light source into heat energy.
