Tensile study of PVC-CdS semiconducting nanocomposite

Thick film of CdS/Polyvinyal cloride (PVC) semiconducting nanocomposite was synthesized by dispersing nanofiller particles of CdS in PVC matrix. The nanostructure of the CdS particles has been ascertained through X-ray Diffraction (XRD). The tensile study of prepared samples has been done through a Dynamic Mechanical Analyzer device. This study reveals that the Young's modulus and the toughness of the material are greatly influenced by the existence of interfacial energetic interaction between dispersed CdS nanofiller particles and matrix of PVC. As a result elastic modulus, toughness and fracture energy are significantly improved in the semiconducting nanocomposite sample.
