Abstract Polyimide (PI) is one of the best engineering plastics with excellent thermal, mechanical, dielectric performance and chemical stability. Among various PI products, film most dominant types. If films are to be applied optical devices display equipment, it necessary improve their transparency in ultraviolet–visible region. However, improving would affect thermal including dimensional Therefore, how balance obtain highly transparent overall becomes a focus current research field. In...

Got a crush: Native cellulose can be dispersed as nanofibers in organic solvents by ball milling with esterification agents. Milling hexanoyl chloride/DMF gives hexanoyl-coated dispersible several solvents. succinic anhydride/DMSO results water-dispersible nanofibers. The open the way to new mechanochemistries. Detailed facts of importance specialist readers are published "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted...

Legal Judgment Prediction is a fundamental task in legal intelligence of the civil law system, which aims to automatically predict judgment results multiple subtasks, such as charge, article, and term penalty prediction. Existing studies mainly focus on impact entire fact description all subtasks. They ignore practical judicial scenario, where judges adopt circumstances crime (i.e., various parts fact) decide results. To this end, paper, we propose circumstance-aware prediction framework...

Metal organic frameworks (MOFs) have unique advantages in optimizing the ionic conductivity of battery separators because their rich cavity structure and highly ordered connected pores. In this study, we used a hydrothermal method to synthesize functional material, Ag-MOF crystal, as separator coating content, then studied properties application effect MOF-Al2O3-blended applying polyethylene (PE) (MOFxAl1-x/PE). Results show that MOF0.08Al0.92/PE (MOF/Al2O3 = 0.08:0.92) NCM811||Li cells...

Chinese spelling check (CSC) is a task to detect and correct errors in text.Most state-of-the-art works on the CSC adopt BERT-based non-autoregressive language model, which relies output independence assumption.The inappropriate assumption prevents BERTbased models from learning dependencies among target tokens, resulting an incoherent problem.To address above issue, we propose novel architecture named Dynamic Connected Networks (DCN), generates candidate characters via Pinyin Enhanced...

The development of high energy density lithium ion batteries puts forward requirements for separators. In this article, poly(vinylidene fluoride-hexafluoropropylene)/Li1.5Al0.5Ge1.5(PO4)3 composite membrane (PL) has been fabricated by electrospinning and with use the dip-coating method as separator battery. With reference to physical properties, PL better mechanical strength than does its base electrospun fluoride-hexafluoropropylene) (PVDF-HFP), thermal stability electrolyte uptake (215%)...

Although lithium metal is extensively used as an anode material for next-generation secondary batteries, the reacts with commonly organic electrolytes, forming dendrites, resulting in short-circuiting of which a safety hazard. Solid-state electrolytes are feasible solution to overcome these limitations. We prepared PI–PEO–LATP composite solid electrolyte by compounding poly(ethylene oxide) (PEO) and Li1.4Al0.4Ti1.6(PO4)3 (LATP) electrospun polyimide (PI) nanofiber membrane using...

In this study, we intend to solve the problem of low glass transition temperature (Tg) and high coefficient thermal expansion (CTE) that colorless polyimide (PI) films always exhibit. First, copolymerized 2,2′-bis(trifluoromethyl)-[1,1′-biphenyl]-4,4′-diamine (TFDB) with 4,4′-(hexafluoroisopropene) diphthalic anhydride (6FDA) p-phthaloyl chloride (TPC) obtained a series transparent (PAI-10). These PAI showed Tg 346–362 °C CTE 25.2–62.9 ppm/K, which were better than those PI6FDA-TFDB....

Li1+xAlxTi2-x(PO4)3 (LATP) is a NASICON-type solid electrolyte that presents stability in aqueous media and high ion conductivity. With these advantages, it expected to be used as cathode separator coating material for lithium-ion batteries improve battery performance. However, also displays level of residual moisture introduction due its strong water absorption. Meanwhile, LATP particle size key influential factor the thereby produces an impact on In this research, we prepared three...

To develop the polyimide (PI) which is closely matched to coefficient of thermal expansion (CTE) copper, a series PIs are prepared from 5,4'-diamino-2-phenyl benzimidazole (DAPBI), 4,4'-diaminodiphenyl ether (ODA), and 3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA) using sequential copolymerization, blade coating, imidization process. The physical properties effectively regulated optimized by adjusting ratio rigid DAPBI flexible ODA components. By increasing content, stability,...

Li1.5Al0.5Ge1.5(PO4)3 (LAGP) is an inorganic solid electrolyte with a Na superionic conductor (NASICON) structure that provides channel for lithium ion transport. We coated LAGP particles on one side of polypropylene (PP) separator film to improve the ionic conductivity separator, and water-dispersed polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) other reduce interfacial resistance between metal anode.

An Al2O3/polyethylene terephthalate (Al2O3/PET) film can be used as a practical battery separator with superior thermostability, but particle shedding inhibits wide application of this material. We developed high-security Al2O3/PET by incorporating photoactive oligomer, poly(ethylene glycol)diacrylate (PEGDA), into the Al2O3 coating, followed ultraviolet (UV) irradiation. One side as-prepared was coated aqueous polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) to obtain...
