Developing dynamic epoxy adhesives (DEAs) with simultaneously strong adhesion, extreme environmental tolerance, and on-demand detachability is in high demand in the future but remains challenging. In this work, we prepared a robust and dynamic epoxy adhesive cross-linked with boroxines, and a small-molecule coupling agent was introduced to coordinate with boroxines to improve its environmental reliability. Owing to the high exchangeability of boroxines and the coordination of amino group with boroxines, the as-developed adhesive shows simultaneously good mechanical properties (tensile strength of 53.55 MPa, fracture toughness of ∼27.3 MJ m–3), excellent lap shear strength (20.5 MPa), good resistance to water (18.8 MPa after soaking in water for 30 days), pH, and high and low temperatures (20.1 MPa at 100 °C, 27.8 MPa at −196 °C), and can be quickly removed and recycled by soaking in specified solvents.

Thermoplastic polyamide elastomers (TPAEs) have emerged as important elastomer materials with significant practical applications, because of their outstanding mechanical properties, good thermal stability, and broad operating temperature window. However, the traditional raw precursors of TPAEs are mainly from fossil materials, which greatly limit their sustainability. To solve this problem, the preparation and application of biobased TPAEs (BTPAEs) have aroused much interest, and a series of achievements have been achieved in the past decades. In this Review, the research progress of BTPAEs is systematically summarized, in which the raw materials, synthesis, properties, and applications of BTPAEs are introduced. In addition, opportunities and challenges for achieving high-performance BTPAEs are presented. This Review is expected to stimulate more unprecedented achievements derived from BTPAEs, thus further promoting their future practical applications.

“…Under natural circumstances, spider silk exhibits unmatched tensile strength and adhesion at very low temperatures. Wu et al [49] synthesized α,ω-dienamide monomers with hydroxydiene (HD), diene butyrate (BD), and carboxydiene (MD), which were further combined with mertan to form polyamide derivatives (cPA). By creating dynamic nanostructures and multistage hydrogen bond networks, the substance maintained the cohesiveness of the system.…”

Comprehensive SummarySpider silk has attracted increasing attention due to its fascinating combination of ultra‐high tenacity high strength, and excellent elasticity. Based on the fundamental biological studies on spider silk, significant research efforts have been devoted to biotechnology and chemical synthesis to mimic or even exceed the properties of natural spider silk fibers. Moreover, the natural spider silk fiber has been simulated with the burgeoning development of numerous spinning technologies, including wet spinning, dry spinning, electrostatic spinning, and microfluidic spinning, which continuously help to optimize the properties of synthetic spider silk. The unique characteristics of natural spider silk include high refraction transmission, heat resistance, antimicrobial properties, biocompatibility, and super shrinking. Biconical recreation of spider silk with special features and extraordinary capabilities demonstrates potential applications in biomedicine, smart wearables, artificial muscles and sensors, aerospace and other domains.This article is protected by copyright.
