We report here novel bifunctionalized electron transport materials (ETMs) that can improve the efficiency and stability of perovskite solar cells (PVSCs) simultaneously. By functionalizing n-type conjugated polymers with fluoro amino side chains, PN, PN-F25%, PN-F50% varied contents chains are prepared. It is found in ETMs efficiently interface contact collection PVSCs, improved power conversion from 14.0% for PC61BM-based devices to more than 17% PN- PN-F25%-based devices. Moreover, endow...
Packaging materials have a great impact on the performance and reliability of light-emitting diodes (LEDs). In this study, we prepared high LED devices through encapsulating LEDs by epoxy incorporated with filler powders. A set evaluation methods also been established to characterize devices. No delamination or internal cracking between packaging lead frames has found for encapsulated after package saturation moisture subsequent exposure high-temperature solder reflow thermal cycling. Four...
Abstract Photocatalytic reduction of CO 2 with H O vapor is gaining increased interest because it a promising “green chemistry” route for the direct conversion to value‐added chemicals driven by solar energy. To increase efficiency photocatalytic conversion, most efforts are made exploring various photocatalysts while little effort on advanced light management. For first time, demonstrated that bio‐degradable transparent paper excellent diffusivity can effectively enhance utilization...
Comprehensive Summary Side‐chain engineering has emerged as a highly effective strategy for tailoring the aggregation behavior and charge transport properties of non‐fullerene small molecule acceptors (SMAs). In this study, we designed synthesized two SMAs, namely BTPSi‐Bu BTPSi‐Pr, respectively incorporating tributylsilyloxy triisopropylsilyloxy groups in their outer positions. Notably, exhibited better planarity, crystallization, favorable phase separation when paired with PM6 donor...
Abstract Dimensionally stable and high strength Polyimide(PI)/nKevlar composite aerogels are fabricated by the inclusion of nano Kevlar fibers with PI precursor polyamide acid via solution mixing subsequent vacuum drying. The rigid macromolecular structure nKevlars intermolecular hydrogen bonding result in lower shrinkage/density larger porosity. PI/nKevlar demonstrate a 23.4% reduction linear shrinkage. Compared pure polyimide aerogel, friction coefficient wear rate aerogel decreased...
ABSTRACT Two novel Salen‐DPCPs metal complexes (Salen‐DPCP‐1 and Salen‐DPCP‐2), containing both Salen‐Schiff base (Salen), phenyl phosphate structures (DPCP) nickel component, were prepared to reduce fire hazards of epoxy resin (EP). The results showed that 5 wt % addition Salen‐DPCP‐1 brought a higher flame‐retardant efficiency the EP, where V‐0 rating in UL‐94 burning test 31.5% limiting oxygen index (LOI) achieved. Meanwhile, total heat release, smoke production, CO yield dramatically...
A novel medium-length fluorinated diols and poly(L-lactide) (PLLA) were synthesized via Michael addition reaction ring-opening polymerization, respectively. Subsequently, Synthetic PLLA combined to prepare new polyurethane composites with degradability low surface energy. The compositional analysis structural characterization of synthetic materials characterized by using fourier transform infrared spectroscopy (FT-IR) proton nuclear magnetic resonance spectra (1HNMR). Thermogravimetric...
A novel poly(methyl methacrylate) (PMMA)‐based copolymer (PMMA‐co‐BDPA) rich in aromatic rings was synthesized via radical copolymerization between a phosphorus‐containing acrylic monomer (BDPA) and methyl methacrylate (MMA). UV‐vis spectroscopy demonstrated that the had high transparency. Thermogravimetric analysis (TGA) differential scanning calorimeter (DSC) were used to test thermal properties of composites. Additionally, PMMA‐co‐BDPA‐15 exhibited 23% increase limited oxygen index (LOI)...
An efficient phosphorous flame retardant rich in aromatic rings was synthesized and introduced into epoxy resin. The properties of the resultant composites were studied, results compared with those 5 wt% tris(bis(4‐((diphenoxyphosphoryl)oxy)phenyl)methyl) benzene‐1,3,5‐tricarboxylate (DHPP‐OH‐BAC), 10 DHPP‐OH‐BAC 15 wt.% samples. showed that 15% sample had best retardancy effect, a limiting oxygen index 33.6%, UL‐94 V‐0 level. A cone calorimeter experiment addition can significantly reduce...
Abstract In this study, a cyclotriphosphazene hyperbranched P/N/Si prepared flame retardant (HBPPSi) was synthesized, and the effects of different loadings HBPPSi on mechanical properties, thermal stability retardancy epoxy resin were investigated.
