Abstract

In recent years, cellulose fibers have attracted considerable attention as biofillers for natural rubber (NR) composites. However, neat cellulose cannot be used as a substitute for conventional fillers due to its poor compatibility with NR. Therefore, a new surface treatment via maleic anhydride grafted to polyisoprene (MAPI) in solution was developed to improve the filler–matrix interaction. Different contents of carbon black (CB) and cellulose fibers (before and after modification) were used as a hybrid filler system to investigate the possibility of CB substitution in NR composites. First, contact angle, Fourier transformed infrared spectrometry (FTIR), and scanning electron microscopy (SEM) techniques were used to confirm the successful cellulose surface treatment. Second, morphological analysis, Payne effect, and swelling behavior of the rubber compounds in toluene confirmed the effect of cellulose treatment on improving the interfacial filler–matrix adhesion. Finally, the results showed that the composite filled with 20 phr modified cellulose and 20 phr CB (50% replacement of CB) exhibited even better results than the composite filled with 40 phr of CB, since the tensile strength was only 7% lower, but the elongation at break, tensile modulus at 100%, and storage modulus at 25 °C were respectively 35%, 24%, and 22% higher.

纤维素纤维表面处理在天然橡胶混杂复合材料中取代炭黑的效果

近年来，纤维素纤维作为天然橡胶(NR)复合材料的生物填料受到了广泛的关注。然而，纯纤维素与NR的相容性较差，不能替代传统的填料。因此，研究了一种新的表面处理方法，即通过马来酸酐在溶液中接枝聚异戊二烯(MAPI)来改善填料与基体的相互作用。采用不同含量的炭黑(CB)和纤维素纤维(改性前后)作为杂化填料体系，考察了炭黑取代NR复合材料的可能性。首先，利用接触角、傅里叶变换红外光谱(FTIR)和扫描电子显微镜(SEM)技术来证实纤维素表面处理的成功。其次，通过形貌分析、Payne效应和橡胶化合物在甲苯中的溶胀行为，证实了纤维素处理对改善填料-基体界面粘附的作用。最后，结果表明，填充20 phr改性纤维素和20 phr CB(替代50% CB)的复合材料比填充40 phr CB的复合材料效果更好，因为拉伸强度仅降低7%，但断裂伸长率，100%拉伸模量和25°C储存模量分别提高35%，24%和22%。
