Mechanical properties of polypropylene nano-composites: An investigation about the correlation with space charge measurements

Sets of nanostructured PP films have been prepared using various techniques and procedures. They have been subjected to mechanical tests (stress-strain curves and to impact strength tests) and have been subjected to electrical space charge tests by means of Pulse ElectroAcoustic techniques. Suitable analysis about the relevant correlations were performed and did produce results useful from the quality control point of view and interesting as regards the production process tuning.
