作为石油基增容剂的替代品，我们开发了具有热塑性的碳纤维增强塑料增容剂木质素衍生物。本研究将不同比例的烷基链引入碱木质素中，以优化碱木质素衍生物与聚丙烯和碳纤维的相容性。掺入优化后的木质素衍生物后，两种材料的界面抗剪强度由8.2 MPa提高到17.2 MPa。该值与典型的石油基增容剂（18.3 MPa）相当。
As an alternative to petroleum-based compatibilizing agents, we developed lignin derivatives for compatibilizing agents of carbon fiber-reinforced plastics that have thermoplasticity. In this study, alkyl chains were introduced into alkali lignin at various ratios to optimize the compatibility of the lignin derivatives with both polypropylene and carbon fiber. The interfacial shear strength between the two materials was improved from 8.2 to 17.2 MPa by mixing with the optimized lignin derivative. The value is comparable to that achieved with a typical petroleum-based compatibilizing agent (18.3 MPa).
