A series flowerlike ZnO-PMMA (FL-ZnO-PMMA) composites were synthesized from PMMA and different amount of flowerlike ZnO (FL-ZnO) particles via the solution direct-dispersing and in-situ polymerization method. FL-ZnO particles have been synthesized using the hydrothermally technique. Effects of synthesis conditions on the crystal structure, crystallite size, microstructure and morphological properties of the produced FL-ZnO particles were investigated by FTIR, X-ray and SEM. The prepared ZnO nanostructures with flowerlike morphology have been blended with methyl methacrylate and this solution was polymerized by in-situ radical polymerization technique to prepare FL-ZnO-PMMA composite films. The obtained nanocomposite films are highly transparent, flexible and chemically stable. Investigation of specific heat capacity of composites is achieved by using differential scanning calorimeter. This study is unique about exploration of effect of FL-ZnO amount on specific heat capacity of polymeric composites.
