Continuous supercritical hydrothermal synthesis of dispersible zero-valent copper nanoparticles for ink applications in printed electronics

Poly(vinylpyrrolidone) – A Versatile Polymer for Biomedical and Beyond Medical Applications

“…PVP has good electrical properties (moderate electrical conductivity and rich physics in charge transport mechanism) [98,106,111,122,127,128] , which made it suitable in various uses in electrical and optical applications, like screens, printed circuit boards [124,126,140] , cathode ray tubes, energy storage devices [123,138] , solar cells, and many others. It is reported that PVP can be used as photoresist in the "black matrix process," where it contributes to a better picture contrast and image resolution in color screen tubes.…”

“…Other metallic nanoparticles coated with PVP used in conducting inks for printed electronics, multilayer ceramic capacitors (MLCC) and magnetic devices were recently reported [124,136,[140][141][142] . Kubota et al used PVP as a surface modifier for synthesizing zero-valent Cu NPs, which are of interest as conductive inks for applications in printed electronics.…”

“…Kubota et al used PVP as a surface modifier for synthesizing zero-valent Cu NPs, which are of interest as conductive inks for applications in printed electronics. The Cu NPs have long-term storage stability and good conductivity (films of 0.33 µm prepared with Cu NPs have a resistivity of 16 μXcm) [140] . Nickel NPs were sintered using PVP as a binder for nanoinks, which can be applied in MLCC electrodes and printed electronics [141] .…”

Synthesis of CuNP-modified carbon electrodes obtained by pyrolysis of paper

“…Although improved performance is commonly reported, the high cost and the limited availability of some of these materials can impose restrictions to the development of sensors for low-income communities. Aiming to address these limitations, other metallic nanomaterials such as copper nanoparticles (CuNPs) have emerged as alternative materials with potential applications in catalysis [17, 18], electronics [19, 20], optics [21], and medicine [22, 23]. Despite their potential toxicity [24], CuNPs are relatively inexpensive and provide access to a number of chemical routes for their derivatization.…”

Continuous Hydrothermal Flow Synthesis of Co1–xNixFe2O4 (x = 0–0.8) Nanoparticles and Their Catalytic Properties for CO Oxidation and Oxygen Evolution Reaction

“…As a result, a high degree of supersaturation is achieved and nucleation starts almost instantaneously upon mixing. To date, various types of nanomaterials prepared by CHFS have been reported, including oxides, metals, sulfides, metal organic frameworks (MOFs), layered double hydroxides, and minerals , . In addition, upscaled operations at industrial level have been proven at pilot scale, in a full commercial plant (Hanwha Chemical Corp., Republic of Korea), and in the European FP7 project SHYMAN (http://www.shyman.eu).…”
