2.6. Thermal characterisation of polymeric materials
All polymeric materials used in the restoration process were characterised by thermal analysis techniques as thermogravimetry (TG) and differential scanning calorimetry (DSC) before and after irradiation with gamma rays. Thermogravimetric measurements were performed using a Shimadzu Corporation thermobalance TGA50 at 201C/min heating rate, from the room temperature reached up to 6001C, under air flow of 50ml/min. The calorimetric measurements were performed using a Shimadzu Corporation DSC 50 at 101C/ min heating rate, in the range from 901C to 3001C depending on the sample, under N2 atmosphere.
