Original Paper


A series of strain, temperature and frequency sweep measurements were performed to systematically study the dynamic rheological properties of polycarbosilance (PCS) in linear viscoelastic region determined by small-amplitude oscillatory shear test. No matter whether during the pre-treated process or testing process, both temperature and holding time have distinct influence in the PCS’s rheological property which can be attested by the changes of critical strain and plateau modulus. A characteristic temperature obtained from the temperature ramp measurement was compared with the softening point temperature of PCS, which is associated with the phase change from solid to melt. PCS exhibited no plateau region in frequency sweep curve and showed a complex thermorheologically melt behavior in time-temperature superposition due to its notably lower molecular weights and complex molecular structures.
