WebBook excerpt: This book delivers a deep insight into thermal polymer degradation features and put a particular emphasis on blends, composites and nanocomposites. It examines the thermal stability and the mechanism of degrading for every class of polymer substances and studies the effect on reinforcement to all classes. WebThe DN ion gels also exhibited a high decomposition temperature of approximately 400 °C because of the thermal stability of all components. Additionally, the fracture energy of the TOCNF/poly(ionic liquid) (PIL) DN ion gel was two times higher than that of the silica nanoparticles/PIL DN ion gel developed in our previous study [Watanabe et al. , Soft …
