AbstractLignin 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 (C4 lignin). Upon the addition of C4 lignin, 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 C4 lignin 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. C4 lignin is a promising candidate for biomass-derived compatibilizing agents for polypropylene-based CFRPs.Butylated lignin was applied as a compatibilizing agent of polypropylene-based carbon fiber-reinforced plastics. The butylated lignin increased the tensile strength of the carbon fiber-reinforced plastic from 37.1 to 40.2 MPa, which was similar to what was achieved with a well-known oil-based compatibilizing agent (40.9 MPa).

丁基木质素作为聚丙烯基碳纤维增强塑料的增容剂

摘要木质素是一种可再生资源，但也被认为是一种废物或价值极低的材料。在此，我们提出了一种木质素衍生的增容剂作为当前增容剂的替代品。我们制备了具有丁基化木质素（C4 木质素）的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以及碳纤维与基体之间的附着力大大提高。因此，用 C4 木质素制备的 CFRP 的拉伸强度大于不含木质素的 CFRP（37.1 与 40.2 MPa 相比）。该值接近于用马来酸酐改性聚丙烯 (40.9 MPa)（一种现有的增容剂）制备的 CFRP 的值。C4木质素是生物质衍生的聚丙烯基碳纤维增强塑料相容剂的一个有前景的候选者。丁基化木质素被用作聚丙烯基碳纤维增强塑料的相容剂。丁基化木质素将碳纤维增强塑料的拉伸强度从 37.1 MPa 提高到 40.2 MPa，这与使用众所周知的油基相容剂 (40.9 MPa) 达到的效果相似。
