<p>Spider silk is an important material in nature, and the relevance of studying the thermal degradation is multifaceted and significant, particularly in the context of materials science and biotechnology. The researchers utilized techniques such as X-ray diffraction, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) to investigate the main characteristics of spider silk and to assess&#xa0;its process of thermal degradation. The thermal stability tests were conducted on the silk at temperatures increasing from 5 to 20&#xa0;°C min⁻¹ in N₂. Data obtained from thermogravimetric analysis were crucial for determining the decomposition activation energy of silk via different kinetic analytical techniques. By applying the theoretical models of Flynn–Wall–Ozawa and Kissinger–Akahira–Sunose, the researchers found the activation energies to be 126.25&#xa0;kJ mol⁻¹ and 140.07&#xa0;kJ mol⁻¹, respectively. The DSC analysis indicated two distinct stages of thermal degradation: an initial stage at lower temperatures, associated with the decomposition of long molecular chains, and a subsequent stage at higher temperatures, linked to the cleavage of glucose rings. Furthermore, TG-FTIR spectroscopic analysis revealed that the main products of decomposition included water, methane, carbon dioxide, and ammonia, among various other compounds.</p>
