  7. Abstract:
  8. Biocompatible materials play a fundamental role in the advancement of medical science and provide groundbreaking solutions for tissue engineering and various therapeutic applications. Among these materials, polyurethane acrylate has attracted attention due to its biocompatibility, versatility, and suitability for creating complex medical scaffolds. This research investigates an innovative approach to reinforce polyurethane acrylate by incorporating graphene quantum dots, with the aim of developing advanced scaffolds for tissue engineering. The incorporation of graphene quantum dots is designed to take advantage of their exceptional properties to improve the mechanical strength, thermal stability, and biocompatibility of polyurethane acrylates, answering the critical demand for high-performance biocompatible materials in medical applications. To investigate the effects of graphene quantum dots on the properties of polyurethane acrylate, nanocomposites with three different percentages (by mass) of 0.1, 0.2 and 0.5% of graphene quantum dots (along with blank nanocomposite as a control sample) were synthesized. And by using various analysis such as FTIR, XRD, TGA, cytotoxicity, mechanical tests, etc., the effects of adding graphene quantum dots on polyurethane acrylate substrate were investigated
