    摘要: The invention is directed to substrates for electronic circuitry. The substrates of the invention have a first polyimide layer having a functional filler and a second polyimide layer having a functional filler. The first layer is non-identical to the second layer, and a surface of the first layer is in contact with and is directly bonded to a surface of the second layer. Filler from each layer extends into the interface between the two layers, and a plurality of covalent bonds are present between the first and second functional layers that chemically bond the two layers together to provide a reliable, predictable multifunctional substrate for electronic circuitry with improved performance relative to polyimide layers bonded together by an adhesive.

    摘要: A back-sheet for a photovoltaic module is provided comprising a fire resistant polymeric film and a second polymeric film adhered to the fire resistant polymeric film. The fire resistant polymeric film comprises a polymer that does not melt at temperatures below 275° C. and an inorganic particulate filler selected from inorganic metal oxides and inorganic metal nitrides, and combinations thereof. The fire resistant polymeric film contains from 40 to 75 weight percent inorganic particulate filler based on the total weight of the film, and the fire resistant polymeric film has an average thickness of at least 85 microns. A photovoltaic module comprising such a back-sheet is also provided.

    摘要: A film is disclosed, containing 40-100 weight percent polyimide. The polyimide is derived from a dianhydride component and a diamine component. The dianhydride component is at least 3,3′,4,4′-biphenyl tetracarboxylic dianhydride (BPDA), and optionally is also pyromellitic dianhydride (PMDA) in a mole ratio of 50-100:50-0 (BPDA:PMDA). The diamine component comprises 1,5-naphthalenediamine (1,5-ND) and 1,4-diaminobenzene (PPD) and/or meta phenylene diamine (MPD) in a mole ratio of 15-95:85-5 (1,5-ND:PPD+MPD). The films have exceptional high temperature storage modulus (elastic modulus) and exceptionally low high temperature creep (eplast).
