A film forming method includes the following (A) to (D). (A) Preparing a substrate having a first region in which a metal film is exposed and a second region in which an insulating film is exposed. (B) Supplying an organic compound, which is represented by Chemical Formula (1) described in the specification, to the substrate, the organic compound containing a triple bond between a carbon atom and a nitrogen atom in a head group and containing a double bond or triple bond between carbon atoms in a chain. (C) Selectively adsorbing the organic compound to the first region among the first region and the second region. (D) Polymerizing adjacent chains of the organic compound, thereby forming a polymer film in the first region.

The invention relates to multi-layer thermoplastic composites, and in particular composites having fluoropolymer in the outer layer and a thermoplastic substrate layer. The fluoropolymer outer layer may either be a layer comprising a majority, and preferably 100 percent fluoropolymer, or may be a blend of a thermoplastic matrix with fluoropolymer at a level of from 5 to 60 weight percent, based on the total weight of all polymers. Especially useful thermoplastic matrices include acrylic polymers, and styrenic polymers, especially styrenic copolymers such as acrylonitrile/styrene/acrylate (ASA), acrylonitrile/butadiene/styrene (ABS) and styrene/acrylonitrile (SAN). While the fluoropolymer may be any fluoropolymer, thermoplastic fluoropolymers, such as polymers and copolymers of polyvinylidene fluoride are especially useful. The improved flame retardant composite of the invention is especially useful in cap layers over plastic substrates, such as for flame-retardant plastic decking, railings, posts, fencing, siding, roofing, and window profiles.

Graphene has been used in nanocomposites as constituents/doping in plastics or epoxy providing dramatic enhancement of the mechanical properties but have not progressed past the laboratory level novelty. This invention can provide a graphene based composite structure with a density less that 1.9 g/cm.sup.3 for a fiber, yarn, rope or cable and a density less that 1.5 g/cm.sup.3 for a sheet both structure have tensile and shear strength greater than either Aluminum or Steel; thus providing a graphene material that is both much lighter and stronger.

A composition is described, which when applied to a surface, where it is desirable for snow and ice not to adhere, promotes release of snow and ice from the tire tread or surface for improved traction and performance. The composition is comprised of a binder polymer, a high molecular weight silicone oligomer or polymer(s) and a suitable delivery system permitting easy application, fast drying and excellent adhesion
