The thermal properties of waste cotton cloths, pulped fiber, bleached fiber, and isolated CNCs were determined using thermogravimetric analysis (TGA/DSC 1 HT, Mettler-Toledo, Colombus, OH, USA). About 8 mg of sample was placed in an aluminium pan, and the sample was then heated from room temperature (28 ± 1 °C) to 800 °C with a heating rate of 10 °C/min and nitrogen gas flow of 50 mL/min. The thermal stability of waste cotton cloths, pulped fiber, bleached fiber, and isolated CNCs was determined using differential scanning calorimetry (DSC) (DSC Q200, TA Instruments, Lukens Dr, New Castle, DE, USA). The changes in weight and heat flow were analyzed.

The thermal stability of neat SMEP and hybrid SMEP was evaluated via thermogravimetric analysis (TGA). The decomposition temperature and rate of decomposition can be obtained from the TGA of nanocomposite samples. The TGA was conducted using a TGA/DSC 1 HT from Mettler Toledo (Columbus, OH, USA), with samples in solid form, of weight between 5 to 10 mg. The test was conducted from room temperature up to 600 °C, with a heating rate of 10 °C/min in a nitrogen atmosphere.

The curing process of the epoxies were monitored under dynamic differential scanning calorimetry (DSC). Heat flow and curing properties can be obtained through DCS analysis. A sample between 5 to 10 mg were prepared for the test. TGA/DSC 1 HT from Mettler Toledo (Columbus, OH, USA) were used with the temperature ranging from room temperature to 150 °C under nitrogen atmosphere at flow rate of 50 mL/min with a heating rate of 10 °C/min
