MXene Enhanced 3D Needled Waste Denim Felt for High-Performance Flexible Supercapacitors

Nano-Micro Letters, Journal Year: 2023, Volume and Issue: 16(1)

Published: Nov. 29, 2023

MXene, a transition metal carbide/nitride, has been prominent as an ideal electrochemical active material for supercapacitors. However, the low MXene load limits its practical applications. As environmental concerns and sustainable development become more widely recognized, it is necessary to explore greener cleaner technology recycle textile by-products such cotton. The present study proposes effective 3D fabrication method that uses fabricate waste denim felt into ultralight flexible supercapacitors through needling carbonization. structure provided sites loading onto Z-directional fiber bundles, resulting in efficient ion exchange between electrolyte electrodes. Furthermore, carbonization process removed specific adverse groups MXenes, further improving capacitance, energy density, power density electrical conductivity of electrodes achieve maximum capacitance 1748.5 mF cm-2 demonstrate remarkable cycling stability maintaining than 94% after 15,000 galvanostatic charge/discharge cycles. Besides, obtained 577.5 cm-2, 80.2 μWh 3 mW respectively. can be used develop smart wearable devices smartwatches, laying foundation novel strategy utilizing cotton high-quality manner.

Microencapsulated phase change material through cellulose nanofibrils stabilized Pickering emulsion templating

Advanced Composites and Hybrid Materials, Journal Year: 2023, Volume and Issue: 6(4)

Published: Aug. 1, 2023

Abstract Phase change materials (PCMs) possess remarkable capability to store and release substantial amounts of energy during the processes melting crystallization across a wide temperature range, thus holding great promise in applications related regulation thermal storage. Herein, effectively address PCM leakage enhance conduction, microcapsules with melamine–formaldehyde resin (MF) shell were prepared using situ polymerization Pickering emulsions stabilized by cellulose nanofibrils (CNFs). CNFs selected as stabilizers for reinforcing nanofillers MF shell, owing their excellent emulsifying capability, high mechanical strength, sustainable nature. Paraffin wax (PW) was utilized material. The resulting shells PW core had diameter ranging from 2 4 µm. Results showed that microcapsule core–shell ratio (Micro-2.0) exhibited highest latent heat fusion, measuring approximately 128.40 J/g 120.23 J/g, respectively. encapsulation efficiency Micro-2.0 determined be 79.84%.
