Abstract

2D transition metal carbides and nitrides (MXenes) have gained much interest in microwave absorption. However, the high conductivity of MXenes results in inferior absorption performance. To solve this problem, Cellulose nanofiber (CNF) is compounded with MXenes to build membranes with biomimetic structures. CNF not only contributes to adjusting the electromagentic parameters, but also enhances the microwave attenuation and regulates the absorption band. In this work, nacre-like and loofah-like carbonized CNF/MXenes membranes were successfully prepared. The self-assembly of CNF and MXene avoids the impedance mismatch, and the biomimetic structures enhance conductive loss, polarization loss and multiple reflection. The results show that nacre-like carbonized CNF/MXene membrane (CCM) exhibits absorbing performance with the minimum reflection loss (RLmin) of −42.2 dB and the Effective absorption band (EAB) of 7.12 GHz. Meanwhile, the absorption peaks are mainly concentrated on X-band. Further, as the morphology changes to porous layers, the RLmin of loofah-like CCM increases to −63.8 dB, whose EAB is 7.32 GHz at 2.5 mm, and the main absorption peaks shift to Ku-band. Besides, the possible absorption mechanism of biomimetic composite membranes has been expounded. This work provides a versatile strategy for CNF/MXene composite membrane with biomimetic structures on excellent and tunable microwave absorption performance.

低温碳化仿生纤维素纳米纤维/MXene复合膜具有优异的微波吸收性能和可调的吸收带
二维过渡金属碳化物和氮化物(MXenes)在微波吸收方面引起了广泛的关注。然而,MXenes的高导电性导致其吸收性能较差。为了解决这一问题,纤维素纳米纤维(CNF)与MXenes复合制成具有仿生结构的膜。CNF不仅可以调节电磁参数,还可以增强微波衰减和调节吸收带。在这项工作中,成功地制备了珠状和丝瓜状碳化CNF/MXenes膜。CNF和MXene的自组装避免了阻抗失配,仿生结构增强了导电损耗、极化损耗和多次反射。结果表明,碳纳米管状CNF/MXene膜(CCM)具有最小反射损耗(RLmin)为- 42.2 dB、有效吸收带(EAB)为7.12 GHz的吸波性能。同时,吸收峰主要集中在x波段。此外,当形貌转变为多孔层时,丝络样CCM的RLmin增加到- 63.8 dB,其在2.5 mm处的EAB为7.32 GHz,主吸收峰移至ku波段。此外,还阐述了仿生复合膜的吸收机理。这项工作为具有优异和可调微波吸收性能的仿生结构的CNF/MXene复合膜提供了一种通用策略。

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.
