Super-stretchable and extreme temperature-tolerant supramolecular-polymer double-network eutectogels with ultrafast in situ adhesion and flexible electrochromic behaviour

Abstract

The current tough and stretchable gels with various integrated functions are mainly based on polymer hydrogels. By introducing a non-covalent supramolecular self-assembled network into a covalently cross-linked polymer network in...

Robust Natural Polyphenolic Adhesives against Various Harsh Environments

“…As a kind of common products in industry, the low cost of epoxy glycidyl ethers would benefit for the further development of robust adhesives (0.05–7.04 USD/g price obtained from Aladdin Biochemical Technology Co., Ltd. would be cheaper in industry from Figure S10a, Supporting Information). Also, those natural polyphenolic adhesives exhibited good low temperature (i.e., the adhesion strength of TA-epoxy adhesives in 25 to −196 °C was stronger than many antifreeze adhesives from Figure S10b, Supporting Information) and simple preparation process compared to many established catechol-based adhesives, − ,− which could be widely used in several kinds of device repairment (i.e., chemical, petroleum, wood, metal, glass, plastic, rubber, and other industries) under different temperatures. Above all, the natural polyphenol-epoxy adhesives developed in the current study could achieve superior performances in different aspects (e.g., robust adhesion, universal adhesion, low price, simple process, low-temperature resistance, and various solvent resistance performances), which were quite interesting for the chemical and industrial fields.…”

A stretchable, compressible and anti‐freezing ionic gel based on a natural deep eutectic solvent applied as a strain sensor

“…Then pulled both specimens at À26 C, the CS4 remained soft and stretchable, and the tensile strengths of the CS4 increased slightly, whereas the fracture strain decreased(Figure 5c), showing a competitive equilibrium between the tensile strength and stretchability. 43…”

Molecular Engineered Crown‐Ether‐Protein with Strong Adhesion over a Wide Temperature Range from −196 to 200 °C

“…Therefore, the established new adhesive system driven by molecular engineering might be an alternative strategy for the advanced fabrication of robust materials employed in multiple high-tech extreme settings, e.g., special equipment under extreme field environments and devices in cosmic space with large temperature fluctuations.
