The effects of lignin chemical structures on the quality lignin-based carbon fibers are still not clear. For this reason, we address challenge by using a simple acid precipitation method to separate and purify study physicochemical characteristics fractionated properties CFs. carried out sequential acidification at different pH levels (10, 8, 6, 4, 2) is indeed effective in obtaining samples with structures, including molecular weights, units' composition ratios, polydispersity indexes...
The moisture-induced malleability of polyimine-based covalent adaptable networks (CANs) enables the thermosets to be reprocessed and recycled at ambient temperature using only water, which leads an energy-neutral green processing materials. This paper provides both experimental theoretical studies understand effects moisture content on kinetics bond exchange reactions (BERs), malleability, in situ softening, damping CANs. study shows that are equivalent affecting time scale network stress...
A simple low-energy method to fabricate lignin-based carbon fibers with excellent mechanical properties<italic>via</italic>electrostatic spinning.
Abstract Covalent adaptable network (CAN) polymers doped with conductive nanoparticles are an ideal candidate to create reshapeable, rehealable, and fully recyclable electronics. On the other hand, 3D printing as a deterministic manufacturing method has significant potential fabricate electronics low cost high design freedom. In this paper, we incorporate composite consisting of polyimine CAN multi-wall carbon nanotubes into direct-ink-writing polymeric sensors outstanding reshaping,...
ABSTRACT In order to optimize the use of residues enzymatic hydrolysis corn stalk (REHCS) and explore low‐cost sustainable raw material substitute for carbon fibers, three types lignin samples were extracted from REHCS by various extraction methods, then they converted into fibers (CFs) electrospinning, thermostabilization, carbonization under same process conditions. The microstructure mechanical properties carbonized different. CFs ethanol organosolv actually smooth brittle films. formic...
The morphological collapse of pure biomass-based carbon fibers is the main challenge restricting its development. Inspiration comes from nature that cellulose and lignin in natural trees are linked by covalent-bonds, leading to good extensibility stability wood. In this work, an effective strategy presented connect cellulose-acetate covalent-bond obtain a novel fiber precursor material. Isophorone diisocyanate was used as chemical modifier successfully through covalent-bond, which formed...
Recycling of engineering thermosets is extremely difficult for conventional techniques due to their crosslinked networks. In this study, we demonstrated a new recycling approach anhydride‐cured epoxy. After soaking the epoxy networks in alcohol solvent mixed with transesterification catalyst, both and catalyst molecules diffused inside, broke ester bonds on chain backbone through bond exchange reactions, eventually decomposed The covalent would be reformed as evaporating solvent, dissolved...
Stretchable strain sensor detects a wide range of variation and is therefore key component in various applications. Unlike traditional ones made elastomers doped with conductive components or fabricated liquid conductors, ionically hydrogel-based sensors remain under large deformations are biocompatible. However, dehydration challenging issue for the latter. Researchers have developed hydrogel-elastomer-based where an elastomer matrix encapsulates hydrogel circuit to prevent its dehydration....
This study reveals the nonequilibrium behaviors of covalent adaptable networks during their topology transition and how will affect network stress relaxation.
Patients with type 1 diabetes and their physicians have long desired a fully closed-loop artificial pancreas (AP) system that can alleviate the burden of blood glucose regulation. Although deep reinforcement learning (DRL) methods theoretically enable adaptive insulin dosing control, they face numerous challenges, including safety training efficiency, which hindered clinical application. This paper proposes safe efficient delivery controller based on DRL. It employed ten tricks to enhance...
Lignin was fractionation extracted by a SFE method to prepare high quality lignin-based carbon fibers.
Abstract In this study, a novel high‐temperature and high‐pressure foam evaluator with variable diameters inner cell cylinder flip function was designed on our own, which can solve the problems such as difficulties in generation inaccurate determination of various parameters by same type instruments, through foaming performance more than 10 betaine surfactants evaluated. The results show that: (1) higher pressure, rate agent stable foam, but stability foamers at low high pressures,...
In this era of rapid development network, the infringement textile industry is becoming more and important, which seriously restricts textiles. paper, a robust digital watermarking method based on chrominance texture features images proposed. The cover image was transformed into CIE LAB color space, B channel extracted. carrier divided blocks, each block by DCT. order to better maintain visual effect robustness watermark, watermark embedded in intermediate frequency domain Then transferred...
