摘要:
The present invention relates to a polyimide-metal laminate that ensures a high adhesion of a metal layer and suitable for use as a material of a high density circuit board. In particular, it provides a polyimide film characterized by having undergone a surface treatment with an alkaline aqueous solution containing a permanganate. The alkaline aqueous solution preferably contains a hydroxide. It also provides a polyimide-metal laminate characterized in that on a surface of the polyimide film a thermoplastic polyimide layer and a metal layer are formed, and a method of producing the polyimide-metal laminate.

摘要:
The invention relates to a method of surface treatment of predetermined areas of a composite material structure with at least one plasma beam at atmospheric pressure, produced by a plasma generator provided with an emission nozzle in order to facilitate its adhesive bonding to another structure, in which: a) the plasma beam emitted through the nozzle may include a reactive gas, is projected on the composite material structure from a distance comprised between 0,2 and 10 cm; b) the plasma beam is projected on the composite material structure with an angle of incidence comprised between 75° and 105°. It is preferably applied to carbon fiber or fiberglass and epoxy resin or bismaleimide resin structures. Other relevant variables in the process are the plasma beam power and the treatment rate.
摘要:
A method of activating a surface of a plastics substrate formed from:
(a) polyaryletherketone such as polyether ether ketone (PEEK) polyether ketone ketone (PEKK), polyether ketone (PEK); polyether ether ketone ketone (PEEKK); or polyether ketone ether ketone ketone (PEKEKK); (b) a polymer containing a phenyl group directly attached to a carbonyl group, for example polybutadiene terephthalate (PBT) optionally wherein the carbonyl group is part of an amide group, such as polyarylamide (PARA); (c) polyphenylene sulfide (PPS); or (d) polyetherimide (PEI);
for subsequent bonding, the method comprising the step of exposing the surface to actinic radiation wherein the actinic radiation: includes radiation with wavelength in the range from about 10 nm to about 1000 nm; the energy of the actinic radiation to which the surface is exposed is in the range from about 0.5 J/cm2 to about 300 J/cm2. Hard to bond substrates are then more easily subsequently bonded for example using acrylic, epoxy or anaerobic adhesive.
