Highly porous composite hydrogel materials β-Ca3(PO4)2/polyethylene glycol diacrylate

Abstract

The possibility of obtaining highly porous composite hydrogel materials for biomedical applications based on tricalcium phosphate in a polyethylene glycol diacrylate matrix, aimed to repair bone defects, was studied. The influence of different contents of inorganic filler particles on the mechanical characteristics of highly porous hydrogel composites β-Ca3(PO4)2/polyethylene glycol diacrylate was studied. The possibility of creating highly porous composite materials with specified elastic properties is demonstrated. The dependence of the viscoelastic properties of the obtained materials on the size of the given porosity is shown. Varying the proportion of tricalcium phosphate in the highly porous hydrogel material makes it possible to control the relative stiffness of the composite.
