Abstract: A polymer matrix based superabsorbent material is provided, which is made of a polymer including nanoparticles with a particle size in the range of 0.1-500 nanometers, one or more water-soluble monomers suitable for radical polymerization, and at least one vinyl alkoxysilane derivative agent as a crosslinker. A method of producing the polymer matrix based superabsorbent material is also provided, which includes steps of: obtaining a solution by adding a solvent to the one or more water-soluble monomers suitable for the radical polymerization, obtaining a reaction mixture by adding the at least one vinyl alkoxysilane derivative agent as the crosslinker to the solution, adding the nanoparticles with the particle size in the range of 0.1-500 nanometers to the reaction mixture, and obtaining the polymer by a polymerization process.
