Preparation and characterization of an acrylic acid modified polyhedral oligomeric silsesquioxane and investigating its effect in a UV curable coating

•POSS bearing acrylate groups was synthesized and optimum molar ratio was found.•The effect of functionality of POSS on properties of resultant coating was studied.•Acrylic modified POSS are less prone to form aggregates in organic matrix.•Introducing POSS into the coating enhance thermomechanical property of coatings.
