#### **2.3 Drying method (according to EN ISO 6330:2000 standard)**

Flat dry – place the samples on a drying rack without stretching the samples. Wait at least 24 hours until completely dry before assessing samples.

### **3. Testing equipment and testing procedures**

#### **3.1 TGA analytical instrument (according to ISO 11358 standard)**

TGA test procedure was followed where 10 to 15 mg of samples were heated from 30 to 500°C at a heating rate of 20°C/min under nitrogen atmosphere.

#### **3.2 DSC analytical instrument (according to ISO 11357-1:2016 standard)**

The DSC instrument was used to evaluate the latent heat of the PCM samples. The samples were cut into small pieces with a sharp blade after which they were spread evenly on the surface of the pans. Some 10 to 15 mg of samples were added to the pan and weighed on the balance which measures up to the accuracy of 0.0001 mg.
