A process for the deposition of a thin film of a desired material on a surface comprising: (i) providing a continuous stream of amorphous solid particles of desired material suspended in at least one carrier gas, the solid particles having a volume-weighted mean particle diameter of less than 500 nm, at an average stream temperature below the glass transition temperature of the solid particles of desired material, (ii) passing the stream provided in (i) into a heating zone, and heating the stream in the heating zone to elevate the average stream temperature to above the glass transition temperature of the solid particles of desired material, wherein no substantial chemical transformation of the desired material occurs due to heating of the desired material, (iii) exhausting the heated stream from the heating zone through at least one distributing passage, at a rate substantially equal to its rate of addition to the heating zone in step (ii), wherein the carrier gas does not undergo a thermodynamic phase change upon passage through heating zone and distribution passage, and (iv) exposing a receiver surface that is at a temperature below the temperature of the heated stream to the exhausted flow of the heated stream, and depositing particles of the desired material to form a thin uniform layer of the desired material on the receiver surface.

A process for the deposition of particulate material of a desired substance on a surface includes: (i) charging a particle formation vessel with a compressed fluid; (ii) introducing into the particle formation vessel a first feed stream comprising a solvent and the desired substance dissolved therein and a second feed stream comprising the compressed fluid, wherein the desired substance is less soluble in the compressed fluid relative to its solubility in the solvent and the solvent is soluble in the compressed fluid, and wherein the first feed stream is dispersed in the compressed fluid, allowing extraction of the solvent into the compressed fluid and precipitation of particles of the desired substance; (iii) exhausting compressed fluid, solvent and the desired substance from the particle formation vessel at a rate substantially equal to the rate of addition of such components to the vessel in step (ii) through a restrictive passage to a lower pressure whereby the compressed fluid is transformed to a gaseous state and a flow of particles of the desired substance is formed; and (iv) exposing a receiver surface to the exhausted flow of particles of the desired substance and depositing a uniform layer of particles on the receiver surface.

When neutralizing the static charges on both sides of a web exiting an unwinding roll, the inside surface of the web may carry a high level of static charge from the unwinding roll to the first conveyance roller. An electrical discharge between the charged inside surface of the web and the first conveyance roller may damage a sensitive, high value coating or layer on the inside surface of the web. Disclosed is a method for suppressing an electrical discharge between the charged inside surface of a web exiting an unwinding roll and a first conveyance roller. The method comprises neutralizing static charges on the outside surface of the unwinding roll using a static dissipater, separating the web from the roll at an unwinding nip, neutralizing a first portion of the static charges on the inside surface of the web to suppress electrical discharges between the web and the first conveyance roller using a static dissipater located near web just before the web touches the first conveyance roller, and neutralizing the remaining second portion of the static charges on the inside surface of the web after the web has exited the first conveyance roller.
摘要:
The present invention generally relates to polymer films and a process for forming a polarizer plate comprising supplying one or more cover sheets on carrier webs, peeling the cover sheet from the carrier webs, spreading the cover sheets, and laminating the cover sheets to a polarizing film. The process may further comprise tension control, static dissipation after peeling the cover sheet from the carrier web, and an accumulator after a double splicing operation for splicing expiring web to fresh web.
