木质素是一种可再生资源，但也被认为是一种废物或非常低价值的材料。在此，我们提出了一种木质素衍生的相容剂来替代现有的相容剂。用丁基化木质素(C4木质素)制备了聚丙烯基碳纤维增强塑料(CFRP)。加入C4木质素后，碳纤维在基体中的分散性和与基体的粘附性都得到了很大的改善。结果表明，含C4木质素的碳纤维复合材料的拉伸强度高于不含木质素的碳纤维复合材料的拉伸强度(37.1 Mpa和40.2 Mpa)。这一数值接近于用现有相容剂马来酸酐改性聚丙烯制备的CFRPS(40.9MPa.9 )。C4木质素是一种很有前途的生物质衍生相容剂，可用于聚丙烯基碳纤维增强塑料。
Lignin is a renewable resource, but it is also considered a waste or a very-low-value material. Herein, we propose a lignin-derived compatibilizing agent as an alternative to the current compatibilizing agents. We prepared a polypropylene-based carbon fiber-reinforced plastic (CFRP) with butylated lignin (C4lignin). Upon the addition of C4lignin, the dispersion of carbon fiber into the matrix, and the adhesion between the carbon fiber and the matrix were greatly improved. As a result, the tensile strength of the CFRP prepared with C4lignin was greater than that of the CFRP without lignan lignin (37.1 compared to 40.2 MPa). This value is close to that of CFRPs prepared with maleic anhydride-modified polypropylene (40.9 MPa), an existing compatibilizing agent. C4lignin is a promising candidate for biomass-derived compatibilizing agents for polypropylene-based CFRPs.
