PATTERNED TRANSPARENT CONDUCTIVE FILM AND PROCESS FOR PRODUCING SUCH A PATTERNED TRANSPARENT CONDUCTIVE FILM
The invention relates to a patterned transparent conductive film, comprising areas with higher conductivity and areas with lower conductivity, wherein in the areas with higher conductivity nanoobjects are disposed in a binder matrix such that the nanoobjects are interconnected and thereby form an area with higher conductivity and wherein in the areas with lower conductivity the nanoobjects are structurally intact and are coated with an insulating coating material. The invention further relates to a process for producing such a patterned transparent conductive film comprising areas with lower conductivity and areas with higher conductivity, comprising following steps: (a) applying an ink comprising electrically conductive nanoobjects and a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer is conductive after drying; (b) drying of the first layer; (c) applying a mixture comprising an insulating coating material or a precursor of an insulating coating material on that parts of the first layer which shall form the areas with lower conductivity, wherein the insulating coating material or the precursors form an insulating coating around the electrically conductive nanowires; (d) drying of the coated substrate.
SUBSTRATE PROCESSING METHOD
In this substrate processing method, a water-repellent treatment is performed on a upper surface of a substrate so as to change the contact angle of pure water with respect to a flat surface to 90 or greater, and then a hydrophobic liquid is supplied to the upper surface of the substrate, thereby replacing a water repellent agent-containing liquid on the upper surface of the substrate with the hydrophobic liquid. After the hydrophobic liquid replacement step, a hydrophilic liquid is supplied to the upper surface of the substrate, thereby replacing the hydrophobic liquid on the upper surface of the substrate with the hydrophilic liquid. After the hydrophilic liquid replacement step, the hydrophilic liquid on the upper surface of the substrate is caused to flow and is removed from the upper surface of the substrate, and the upper surface of the substrate is thereby dried.
Method for injecting strand-blocked cable
A method for rejuvenating a strand-blocked cable having a conductor comprised of a plurality of conductor strands with interstitial volume therebetween blocked by a PIB based strand-block mastic, the conductor being surrounded by a polymeric cable insulation. The method including pre-injection of compressed gas into the conductor strands of the cable at a pressure less than the elastic limit of the cable insulation, and injection of a rejuvenation fluid into the conductor strands of the cable at a pressure less than the elastic limit of the cable insulation.
Programmable deposition of thin films of a user-defined profile with nanometer scale accuracy
An inkjet-based process for programmable deposition of thin films of a user-defined profile. Drops of a pre-cursor liquid organic material are dispensed at various locations on a substrate by a multi-jet. A superstrate is held in a roll-to-roll configuration such that a first contact of the drops is made by a front side of the superstrate thereby initiating a liquid front that spreads outward merging with the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate then occurs after a duration of time. The contiguous film is then cured to crosslink it into a polymer. The superstrate is then separated from the polymer thereby leaving a polymer film on the substrate. In such a manner, non-uniform films can be formed without significant material wastage in an inexpensive manner.
Device for coating a fiber and a method for coating a fiber and a fiber
A device for coating a fiber includes a fiber receiving arrangement and a coating arrangement which includes an application unit which wets the fiber with a coating agent, and a curing unit arranged downstream of the application unit which optically cures the coating agent. The curing unit includes a lamp which emits at least one light beam which is aimed directly or indirectly at a surface of the fiber.
