2.5. Dynamic Scanning Calorimetry

The crystallinity and the crystallization temperature of the coated powders are determined by differential scanning calorimetry (DSC). For this purpose, a Polyma 214 (Netzsch, Selb, Germany) is used. The samples with a weight of 10 mg ± 0.1 mg are measured with covered aluminum pans type Concavus Lids (Al), NGB817526 (Netzsch, Germany) with dry nitrogen gas purging at 40 mL min⁻¹. As the melting temperature of the PP is at 186 °C, the temperature profile to measure the thermogram is as following: (1) Start at 20 °C, (2) heating to 200 °C by a gradient of 10 K min⁻¹, (3) isothermal step of 60° s, (4) cooling by a gradient of 10 K min⁻¹.
