Mechanochromic, Shape‐Programmable and Self‐Healable Cholesteric Liquid Crystal Elastomers Enabled by Dynamic Covalent Boronic Ester Bonds

Angewandte Chemie International Edition, Год журнала: 2021, Номер 61(9)

Опубликована: Дек. 28, 2021

Endowing a cholesteric liquid crystal elastomer (CLCE) exhibiting helicoidal nanostructure with dynamically tailorable functionalities is of paramount significance for its emerging applications in diverse fields such as adaptive optics and soft robotics. Here, mechanochromic, shape-programmable self-healable CLCE judiciously designed synthesized through integrating dynamic covalent boronic ester bonds into the main-chain polymer network. The circularly polarized reflection CLCEs can be reversibly tuned across entire visible spectrum by mechanical stretching. Thanks to introduction bonds, were found show robust reprogrammable self-healing capabilities. research disclosed herein provide new insights development 4D (color 3D shape) programmable photonic actuators towards bioinspired camouflage, optical systems, next-generation intelligent machines.

Probing and Manipulating Noncovalent Interactions in Functional Polymeric Systems

Chemical Reviews, Год журнала: 2022, Номер 122(18), С. 14594 - 14678

Опубликована: Сен. 2, 2022

Noncovalent interactions, which usually feature tunable strength, reversibility, and environmental adaptability, have been recognized as driving forces in a variety of biological chemical processes, contributing to the recognition between molecules, formation molecule clusters, establishment complex structures macromolecules. The marriage noncovalent interactions conventional covalent polymers offers systems novel mechanical, physicochemical, properties, are highly dependent on binding mechanisms that can be illuminated via quantification. This review systematically discusses nanomechanical characterization typical polymeric systems, mainly through direct force measurements at microscopic, nanoscopic, molecular levels, provide quantitative information (e.g., ranges, strengths, dynamics) behaviors. fundamental understandings intermolecular interfacial then correlated macroscopic performances series noncovalently bonded polymers, whose functions stimuli-responsiveness, self-healing capacity, universal adhesiveness) customized manipulation providing insights into rational design advanced materials with applications biomedical, energy, environmental, other engineering fields.

Magnetic Dynamic Polymers for Modular Assembling and Reconfigurable Morphing Architectures

Advanced Materials, Год журнала: 2021, Номер 33(30)

Опубликована: Июнь 19, 2021

Abstract Shape‐morphing magnetic soft materials, composed of particles in a polymer matrix, can transform shape reversibly, remotely, and rapidly, finding diverse applications actuators, robotics, biomedical devices. To achieve on‐demand sophisticated morphing, the manufacture structures with complex geometry magnetization distribution is highly desired. Here, dynamic (MDP) composite hard‐magnetic microparticles network thermally responsive reversible linkages, which permits functionalities including targeted welding for magnetic‐assisted assembly, reprogramming, permanent structural reconfiguration, reported. These functions not only provide desirable material programmability reprogrammability but also enable manufacturing functional architected materials such as 3D kirigami distribution. The modular assembly be further combined reprogramming reshaping capabilities programmable reconfigurable architectures morphing structures. reported MDP are anticipated to new paradigm design future multifunctional assemblies

Abstract Solar‐driven interfacial evaporation has emerged as an innovative and sustainable technology for efficient, clean water production. Real‐world applications depend on new classes of low‐cost, lightweight, robust materials that can be integrated into one monolithic device, which withstands a variety realistic conditions open water. Self‐repairing building blocks are highly desired to prevent permanent failures, recover original functions maintain the lifetime steam generators, although related studies scarce date. For first time, monolithic, durable, self‐floating generator with well‐defined structures is demonstrated by integrating self‐healing hydrogels through facile processes in surface modulation device fabrication. High stable rates over 2.0 kg m −2 h −1 attained under 1 sun both fresh brine broad range salinity (36–210 g ). The solar desalination performance among best‐performing generators surpass majority devices constructed composite polymers structural components. This study provides perspective highlights future opportunities damage‐tolerant simultaneously improve performance, durability, real‐world applications.
