Abstract Owing to their ease of fabrication, low cost, and high flexibility, organic materials have attracted great interests in photodetector (PD) applications. However, suffering from large dark current, small photocurrent, on–off ratio, sensitivity, performances bare organic‐based PDs are not satisfactory. Integrating with other novel semiconductor offers an opportunity overcome these drawbacks. Here, a lateral hybrid organic/lead sulfide (PbS) quantum dot bilayer PD is designed...
Low-temperature curable negative-tone photosensitive polyimide (n-LTPI) viscous solutions were prepared by dissolving photo-crosslinkable poly (amic ester) (pc-PAE) resin, photophotocrosslinker, photoinitiator, and the heteroaromatic base as curing catalysts, other additives in organic solvents. Among them, pc-PAE resin was synthesized polycondensation of aromatic diacid chloride diester 2-ethoxymathacrylate, diamines aprotic After being spun-coated on a silicon wafer surface, soft-baked,...
Abstract Owing to their attractive performance in photovoltaic devices, organolead halide perovskite materials have attracted enormous interest for photodetector applications. However, current perovskite‐based photodetectors mainly rely on high‐conductive 2D such as graphene or transition metal sulfides transport photocarriers, which indeed significantly improve the photoresponsivity but seriously weaken other parameters on/off ratio response speed. Achieving a high overall remains...
Because of high conductivity, acceptable cost and good screen-printing process performance, silver pastes have been extensively used for making flexible electronics. However, there are few reported articles focusing on heat resistance solidified their rheological properties. In this paper, a fluorinated polyamic acids (FPAA) is synthesized by polymerization the 4,4'-(hexafluoroisopropylidene) diphthalic anhydride 3,4'-diaminodiphenylether as monomers in diethylene glycol monobutyl. The nano...

Abstract Morphological structures of epoxy resin toughened by a fluorinated polyimide were observed SEM. Three layers formed spontaneously parallel to the film surface in range weight fraction w = 0.14–0.20, when samples cured at 130 °C. The two outer consisted mostly epoxy‐rich phase. middle layer bicontinuous domains polyimide‐ and phases with characteristic domain size much smaller than thickness. At 0.10–0.13, aggregates polyimide‐rich particles formed. Observation morphological...
Meltable thermoplastic polyimide resins (MTPI) with designed polymer backbones and controlled molecular weights for advanced microelectronic packaging substrate application have been synthesized by thermal polycondensation of aromatic dianhydride diamine in presence endcapping agent. The could be dissolved organic solvents to give low viscosity solutions, which were then employed impregnate E-glass cloth (EG) yield MTPI/EG prepregs. After removal the volatile, prepregs plied up melt...
Based on some recent works about the general solution of fractional differential equations with instantaneous impulses, a Caputo-Hadamard equation noninstantaneous impulses is studied in this paper. An equivalent integral undetermined constants obtained for order system which means that there impulsive systems. Next, an example given to illustrate result.
Abstract Novel‐fluorinated poly(etherimide)s (FPEIs) with controlled molecular weights were synthesized and characterized, which used to toughen epoxy resins (EP/FPEI) carbon fiber‐reinforced composites (CF/EP/FPEI). Experimental results indicated that the FPEIs possessed outstanding solubility, thermal, mechanical properties. The thermally cured EP/FPEI resin showed obviously improved toughness impact strength of 21.1 kJ/m 2 elongation at break 4.6%, respectively. also tensile 91.5 MPa...
