摘要:
A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system.
摘要:
A method for improving the adhesion of a functional coating to an article formed of compressed particles of exfoliated graphite, which includes applying a primer coating to the article, where the primer coating has as its constituents at least some of the constituents of the functional coating and exhibits greater adhesion to the article than does the functional coating.
摘要:
The present invention relates to thermoplastic hollow vessels, tanks, drums and other industrially applicable housings. The invention is adaptable as plastic fuel tanks with low fuel permeability, e.g., less than 5 g.·mm/m2 day as a mono-layer structure. These vessels exhibit good sub 0 0C impact properties and are formed by relatively inexpensive blow molding or rotomolding processes. Disclosed are mono-layered hollow vessels comprising an uncompatibilized, fused blend composition of polyoxymethylene, thermoplastic polyurethane and a copolyester. In one embodiment mono-layered hollow vessels comprise uncompatibilized, fused polyoxymethylene, thermoplastic polyurethane and copolyester in the respective wt. amounts of 100, 5-15 and 5-15. According to a more preferred aspect the wt. ratio of thermoplastic polyurethane to copolyester is from 1:3 to 3:1.
摘要:
An improved method enables preparation of articles for a variety of applications, including embossing or otherwise shaping to form a variety of articles. A plurality of thin, preferably resin-impregnated, flexible graphite sheets are arranged to form zones in a composite material having a graded density or other characteristic. Variation of properties between zones in the stock material formed is useful for achieving a desired set of properties in the formation of articles such as those useful in electrochemical fuel cells and double-layer capacitors.

A process for producing a flexible graphite sheet having two major surfaces includes compressing particles of exfoliated graphite to form a sheet; impregnating a resin composition into the sheet so as to form a resin-impregnated sheet; curing the resin-impregnated sheet; and thereafter treating the cured, resin-impregnated sheet to provide a structure thereon or therein.

摘要:
A flexible graphite sheet material having improved molding characteristics is provided by effecting resin impregnation such that the resin profile across one of the dimensions of the sheet is non-uniform.
摘要:
Composites are prepared from resin-impregnated flexible graphite materials. Impregnated materials are compressed and cured at elevated temperature and pressure to form structures suitable for uses such as electronic thermal management (ETM) devices, supercapacitors and secondary batteries.
