*2.2.7. Thermomechanical analysis (TMA)*

The thermal expansion tests of the composites and pure polyolefine samples were conducted using a thermomechanical analyzer (TMA Q400 V7.4 Build 93, TA Instruments) from −10 to 100°C at a heating rate of 2°C/min in a nitrogen atmosphere. The expansion mode with a constant compression load of 0.02 N was used on specimen of 5 mm × 5 mm × 4 mm.
