Direct Ink Writing of Flexible Electronics on Paper Substrate with Graphene/Polypyrrole/Carbon Black Ink

Flexible Carbon‐Based 3D Conductive Network Structure Blade‐Coated on Poly(ethylene terephthalate) Substrate for Light‐Emitting Electronic Devices

“…With the development of modern printed electronics technology, conductive ink as an especial functional composite has rapidly developed into one of the pivotal materials. [1] Metal particles (such as silver, [2][3][4] copper, [5] and gold [6,7] ) or carbon-based particles (such as graphene, [8] carbon black, [9] and carbon nanotubes [10] ) are as conductive fillers distributed in an insulating polymer matrix to formulate conductive inks. In recent years, carbon-based fillers have attracted a great deal of interest in the field of electrically conductive polymer composite because of their ability to improve performance at low filler concentration, relatively good interfacial bonding with polymer, and availability in different forms (hydrogen bonding, chemical covalent bonding, etc.).…”

“…[18][19][20] Adding carbon black to a polymer can achieve different ranges of resistivity (10-10 À1 Ω cm), [21] thus having a wide range of applications such as flexible conductive films, sensors, conducting electrodes, and electronic industry. [9,16,22] Graphite also has been widely studied as a conductive filler for polymer matrixes. [23] It belongs to the hexagonal crystal system, which is lamellar or scaly, or powder.…”

Optimization parameters effects on electrical conductivity of 3D printed circuits fabricated by direct ink writing method using functionalized multiwalled carbon nanotubes and polyvinyl alcohol conductive ink

“…Direct ink writing (D.I.W) method, one of the types of 3D printing technology has attracted researchers in recent years and has been recognised as an advanced fabrication technology because of the wide scope of applications in manufacturing flexible, wearable electronic circuits and components [1][2][3][4][5] e.g., printing flexible circuits [6,7], wearable electronics [8,9], super capacitors [10,11], batteries [12,13], strain sensor [14,15], energy harvesting devices [16,17], touch screens [18,19], bio sensors [20][21][22]. This D.I.W technology advances in the fabrication of complex electronic circuits by adopting pneumatic extrusion process [23][24][25] by formulating ink with controlled rheology [26][27][28].…”

“…Printability of inks is very essential in D.I.W as they determine the performance of fabricated parts. In printed electronics, conductive inks can impart flexibility [4][5][6][7][8]11,32], mechanical robustness and electrical conductivity [15][16][17][18][19]33]. Many researchers have fabricated electronic circuits by D.I.W method with printable inks which are composites of nano fillers like CNT, graphene, carbon black, silver inks and polymers like polyvinyl alcohol (PVA), polydimethylsiloxane (PDMS), polyvinylidene fluoride (PVDF), polyaniline (PANI) [11,14,15,18,22,34,35].…”
