Abstract

Adhesive tapes with strong adhesion and triggerable detachment are highly desirable in diverse functional applications. However, existing designs often face limitations such as harsh detaching conditions, complex synthesis, and adhesive residues. Inspired by the formation and removal of scabs, a facile strategy is proposed to design strong adhesive tapes with water-triggered self-detachment based on the crystallization and melt/dissolution of polyethylene glycol (PEG). Owing to the crystallization-induced interfacial reinforcement, the PEG-based elastomers achieve high adhesive strength (0.81 MPa) and instant adhesion. Moreover, the elastomers can self-detach upon water immersion due to the water-mediated destruction of PEG crystals. Compared to other reported adhesive tapes with mild detaching triggers, the elastomers display superior performance with high adhesive strength and negligible residual strength, allowing for intelligent applications of reusable smart tapes. It is believed that this work can inspire the novel design of switchable adhesives.

基于水介导的聚合物晶体破坏的自脱离的结痂激发的强力胶带。

具有强附着力和可触发分离的胶带在各种功能应用中是非常理想的。然而，现有的设计经常面临诸如苛刻的分离条件，复杂的合成和粘合剂残留等限制。受结痂形成和去除的启发，研究人员提出了一种基于聚乙二醇（PEG）的结晶和熔融/溶解，设计具有水触发自脱离的强力胶带的简单策略。由于结晶引起的界面增强，聚乙二醇基弹性体具有较高的粘接强度（0.81 MPa）和瞬时粘接性能。此外，由于水介导的PEG晶体破坏，弹性体在水浸泡时可以自分离。与其他报道的具有轻微分离触发的胶带相比，弹性体具有高粘合强度和可忽略不计的残余强度，具有卓越的性能，允许可重复使用的智能胶带的智能应用。相信这项工作可以启发可切换胶粘剂的新设计。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
