Restricted chain segment mobility in poly(amide) 6/clay nanocomposites evidenced by quasi-isothermal crystallization

摘要: Modulated temperature differential scanning calorimetry is used to explore the interactions between a poly(amide) 6 matrix and various types of clay reinforcement. During quasi-isothermal crystallization polymer/clay nanocomposites, an excess contribution observed in recorded heat capacity signal, due reversible melting crystallization. It proposed that magnitude this can be qualify interfacial interaction, as it directly linked segmental mobility polymer chains interphase region, where both crystalline amorphous fractions are affected. shown interaction strongly depends on type filler used. These play key role development specific material properties for different nanocomposites. A simple model 6/clay nanocomposites proposed.
