Embodiment Construction

[0031] refer to figure 1 , figure 1 (a) represents a porous membrane 10, for example, a hydrophilic nitrocellulose membrane (NCM) having a pore diameter of approximately 25 nm. figure 1 (b) shows a hydrophobic mask 12 printed onto the porous membrane, for example a wax printed mask (WPM) with a height of approximately 25 μm. The mask 12 follows a pattern complementary to the desired pattern of the electronic device or structure 20 (see figure 1 b and figure 1 e) and leaving corresponding openings 11 reaching the surface of the diaphragm 10 .

[0032] figure 1 (c) shows the electronic material 22 deposited on the non-printed area of ​​the porous membrane 10 due to vacuum filtration of the suspension of the electronic material, such as non-conductive graphene oxide (oGO), through the porous membrane, The suspension, for example an aqueous suspension, is on the non-printing area, that is, on the opening 11 left by the mask 12 . That is, a liquid such as water is filtered th...

Abstract

A method of forming an electronic device on a flexible substrate and an apparatus including the electronic device. A method for forming an electronic device (20) on a flexible substrate (30) without using an acetone solvent, comprising the steps of: printing a hydrophobic mask (12) on a porous membrane (10) to A pattern complementary to the desired pattern is formed on the porous membrane; an aqueous suspension of electronic material (22) is filtered through the non-printed area (11) of the porous membrane, thereby depositing on the non-printed area following the desired pattern press the flexible substrate against the printing surface of the membrane to transfer the patterned electronic material deposited on the porous membrane to the flexible substrate to form thereon the electronic device.

Description

technical field [0001] The present invention relates to methods of forming electronic devices on suitable flexible substrates and devices comprising electronic devices fabricated by such methods. Such a device may be, for example, an electrode or an array of electrodes or (more commonly) an electronic platform. Background technique [0002] Devices of this type can be used to make solar cells, light-emitting diodes (LEDs), field-effect transistors (FETs), supercapacitors, biosensors, and more. An interesting material for such devices is graphene oxide (GO), oxidized (oGO) or reduced (rGO), but other materials can also be used, as for example gold nanoparticles, carbon nanotubes, CdSe Or CdTe quantum dots, or even composites. [0003] Oxidized graphene oxide (oGO)-based platforms are driven by spin-coating, self-assembly, vacuum filtration, or solvent exchange and can be patterned using nanolithography, microcontact, or inkjet techniques. These methods involve long manufac...
