“…The screen printing process has the ability to deposit thick layers of viscous slurries be they conductive metals or carbons, or indeed insulators and dielectrics, with high functional material loadings, and hence performance for the various applications. Carbon inks for screen printing are a commercially established technology, particularly in applications such as blood glucose sensors and while there is some literature on the influence of conductive carbon ratios in paints and composites [9,13,14], there is a lack of published literature into the interaction between graphite and carbon black and the effect of the ratios of these ingredients in inks. An abundance of composites studies uses the classical percolation theory to model electrical properties alongside experimental testing, but these only consider single types of carbon in any system [15,16].…”

Conductive inks based on graphite and carbon black are used in a host of applications including energy storage, energy harvesting, electrochemical sensors and printed heaters. This requires accurate control of electrical properties tailored to the application; ink formulation is a fundamental element of this. Data on how formulation relates to properties have tended to apply to only single types of conductor at any time, with data on mixed types of carbon only empirical thus far. Therefore, screen printable carbon inks with differing graphite, carbon black and vinyl polymer content were formulated and printed to establish the effect on rheology, deposition and conductivity. The study found that at a higher total carbon loading ink of 29.4% by mass, optimal conductivity (0.029 X cm) was achieved at a graphite to carbon black ratio of 2.6 to 1. For a lower total carbon loading (21.7 mass %), this ratio was reduced to 1.8 to 1. Formulation affected viscosity and hence ink transfer and also surface roughness due to retention of features from the screen printing mesh and the inherent roughness of the carbon components, as well as the ability of features to be reproduced consistently.

“…Epoxy resins are also found in other applications such as shielding electromagnetic/radio frequency interferences and in dissipating static charges. Azim et al [4] reported about a composite of polysulfide modified epoxy resin cured with a polyethylene polyamine and carbon based electro-conducting fillers. They showed that at an amount of 55 vol.% of conductive filler in the composite, consisting of 85 % graphite and 15% carbon black, the material had a specific volume resistance 2*10 -5 Ohm*m.…”

“…Accordingly, the variety of metalizing techniques on textile substrate was utilized to promote their properties for technical applications. The metal coating on fabric substrate is possible to be carried out using range of techniques including spraying of conductive paint [21], sputter coating [22] and electroless plating [13,[22][23][24][25]. Among the cited coating techniques, electroless plating is of special interest due to its advantages such as uniform and coherent metal deposition, good electrical conductivity and efficient heat transport.…”

Rejection of far infrared radiation from the human body using Cu–Ni–P–Ni nanocomposite electroless plated PET fabric

An experimental investigation was utilized to present the IR rejection performance of Cu-Ni-P-Ni composite double-layer electroless plated PET fabric compared to fabric samples composed of Cu-Ni-P metallic monolayer. Accordingly, the effect of a range of operational parameters was explored on the conductivity of electroless plated PET fabric. Results indicate higher conductivity and lower durability for Cu-Ni-P-coated samples compared to its counterpart with same sub-layer included with nickel on top layer. The SEM image of CuNi-P particle on PET fabric shows a hexagonal non-homogenous morphology with nanoscale crack on its surface. However, the micrograph of the Cu-Ni-P-Ni electroless plated fabric shows an extremely compact and continuous phase with clear boundaries containing semispherical particles. The thermopile radiated sensing system was used as a sophisticated device to show the thermal energy absorption level. The acquired data indicate a 2.3 and 2.7 unit reduction in transmitted radiated power, respectively, for Cu-Ni-P and Cu-Ni-P-Ni conducting fabric. The captured thermal camera images of human body while keeping in front of a Cu-Ni-P conducting fabric revealed a nearly black and blue feature which proves the significant decrease in body radiated thermal energy. However, the thermal image of Cu-Ni-P-Ni conductive fabric shows almost black appearance in all areas. It can be presumably due to improving of the IR rejection performance and also formation of a massive barrier against body thermal radiation for promising camouflage applications.
