摘要: The influences of acetone extract (AE) from natural rubber on the interface structure of NR/CB composites were investigated through rubber process analyzer (RPA), scanning electron microscopy (SEM), Raman spectroscopy, X-ray diffraction (XRD), and differential scanning calorimetry (DSC). The results demonstrated that the crystallite size of CB was increased by AE, leading to the decrease of dispersive free energy (gamma(d)(s)) on the CB surface, which results in a reduction of CB-NR interaction. Oppositely, AE also increased the number of physical entanglement points in NR/CB matrix for its polarity interaction with CB, which could promote the CB-NR interaction. Consequently, the optimized value of AE in NR/CB matrix is 2 phr, where the optimal mechanical and dynamical properties were obtained. Simultaneously, AE had a negative effect on the strain-induced crystallization behaviors of NR/CB composites. This research may draw attention to the evaluation of quality standards of NR.
