Abstract

Gels, as appealing materials for soft electronic devices, often face the great challenge of inherent defects in the solvents, inducing their weak mechanical performance, environmental instability, and limited applications. Herein, multifunctional wood-based eutectogels are developed in the presence of green polymerizable deep eutectic solvents (PDESs, consisting of choline chloride, ChCl; acrylic acid, AA; acrylamide, AM), and reinforced by the tannic acid-encapsulated wood skeleton (TA@WS). The study highlights a green synthesis strategy of solar polymerization without using any chemical initiators or cross-linkers, and overcomes the critical limitations of environmental instability and poor mechanical performance of gel materials. In particular, the developed wood-based eutectogels simultaneously show a high tensile strength of 52.8 MPa and environmental tolerance from −80 ℃∼200 ℃, surpassing most of the reported wood-based gel materials. Moreover, the synergy between TA@WS and PDES endows the wood-based eutectogels with additional self-healing performance, adhesion properties, easy-recyclability, heat-insulation, and electrical conductivity. Benefitting from these features, the developed multifunctional wood-based eutectogels hold great promise in advanced energy applications such as wearable sensors, recyclable materials and smart house construction materials.

无引发剂太阳能聚合绿色合成多功能木基共凝胶
凝胶作为软性电子器件的理想材料,往往面临溶剂固有缺陷的巨大挑战,导致其机械性能弱,环境不稳定,应用范围有限。在此,在绿色可聚合的深度共晶溶剂(pess)的存在下,开发了多功能木基共凝胶,包括氯化胆碱,ChCl;丙烯酸AA;丙烯酰胺,AM),并通过单宁酸封装的木骨架(TA@WS)加强。该研究强调了一种不使用任何化学引发剂或交联剂的太阳能聚合绿色合成策略,并克服了凝胶材料环境不稳定性和机械性能差的关键限制。特别是,开发的木基共凝胶同时具有52.8 MPa的高抗拉强度和−80℃~ 200℃的环境耐受性,超过了大多数报道的木基凝胶材料。此外,TA@WS和PDES之间的协同作用赋予木质共凝胶额外的自愈性能、粘附性能、易于回收、隔热和导电性。得益于这些特点,开发出的多功能木质共聚物在可穿戴传感器、可回收材料和智能房屋建筑材料等先进能源应用中具有很大的前景。

期刊介绍: The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
