摘　　要：Adhesives play an important role in modern society's production and daily life.Developing robust and sustainable adhesives remains a great challenge.Here we report a sustainable epoxy-vitrimer adhesive with high adhesive strength(about 10 MPa)and reusability(82%strength after 3 times).This adhesive can be fabricated from commercially available products through a straightforward hot-pressing method without the need of solvents.The adhesive process is also simple,requiring only 30 min at 180℃.In addition,the vitrimer adhesive has the advantages of both erasability for reuse and excellent water resistance.This work provides a facile strategy to fabricate high-strength adhesive that ensures reusability,recyclability,low cost of raw materials,and simple processing technology.Simultaneously,it expands the range of potential applications for epoxy vitrimers.
