Lignin‐Reinforced Ethylene‐Propylene‐Diene Copolymer Elastomer via Hydrogen Bonding Interactions

摘要

Abstract It is still a great challenge to prepare lignin/polyolefin composites with good strength and toughness. Inspired by the energy sacrificial mechanism from biomaterials, dynamic hydrogen bonds (H‐bonds) are incorporated into the lignin/ethylene‐propylene‐diene monomer (EPDM) composite system to improve the interfacial interactions between lignin and EPDM. Such H‐bonding interactions are demonstrated to be able to simultaneously improve the modulus, strength, and toughness of lignin/EPDM composites without sacrificing the extensibility. This work provides a facile method for the high‐valued utilization of lignin in the preparation of high‐performance elastomer composites using bio‐renewable resources as reinforcing agent.
