A continuous method for making a nanostructured surface comprises (a) placing a substrate comprising a nanoscale mask on a cylindrical electrode in a vacuum vessel, (b) introducing etchant gas to the vessel at a predetermined pressure, (c) generating plasma between the cylindrical electrode and a counter-electrode, (d) rotating the cylindrical electrode to translate the substrate, and (e) anisotropically etching a surface of the substrate to provide anisotropic nanoscale features on the surface.
摘要:
A method of making a coated film comprises coating a first side of a base film with a coating material to form the coated film; wherein the base film was formed in a calendaring process, and wherein, during the calendaring process, the first side physically contacted less surface area of a first roll than a second side physically contacted of a second roll at a given time; and wherein the coated film has an uncoated second side.
摘要:
Disclosed is a method for preparing a laminate less than or equal to about 98 micrometers in thickness and having substantially diminished curling which comprises the steps of (i) providing a metal foil, a thermoplastic resin film and a woven fabric, and (ii) laminating the thermoplastic resin film between the metal foil and woven fabric, wherein the combination of thermoplastic and fabric has a coefficient of thermal expansion that differs from the coefficient of thermal expansion of the metal foil by less than about 30 ppm. Also disclosed are laminates comprising a thermoplastic resin film between a layer of metal foil and a layer of woven fabric. Also disclosed are laminates consisting of either a polyetherimide film and a woven glass fabric or consisting of a layer of woven glass fabric with a layer of polyetherimide film laminated to each side of the fabric. Articles comprising a laminate of the invention are also disclosed.
