A method for forming a protective film includes directly or indirectly coating only a periphery of a substrate with a composition. The composition includes a compound having an aromatic ring, and a solvent. The solvent includes a first solvent having a normal boiling point of 156° C. or higher and lower than 300° C. A content of the first solvent in the solvent is preferably 20 mass % or more and 100 mass % or less. The first solvent is preferably an ester, an alcohol, an ether, a carbonate, or a combination of two or more of an ester, an alcohol, an ether, and a carbonate.

Described herein are branched and hyperbranched anionic phenylene polymers, produced with controlled incorporation of anionic substituents. Applications of such branched ionomeric polymers are also described herein. The branched ionomeric polymers are prepared by a convenient and well-controlled method, permitting tailored properties of catalyst ink formulations, ionomeric polymer membranes, and other applications. Such branched ionomeric polymers have applications in water purification, fuel cells, and battery products.

A method for depositing Parylene onto a substrate includes operating a first pyrolysis chamber at a first set of parameters to cause cracking of dimers into monomers at the first set of parameters and operating a second pyrolysis chamber at a second set of parameters to cause cracking of dimers into monomers at the second set of parameters. The method includes mixing the monomers at the first set of parameters with monomers at the second set of parameters together and polymerizing the mixture as a protective coating.

The disclosure relates to a method of making carbon fiber, the method comprising pyrolyzing poly(p-phenylene) (PPP) fiber at a temperature sufficient to convert PPP fiber substantially to carbon fiber. The disclosure also relates to pre-PPP polymer, methods for making PPP fiber from pre-PPP polymer and, in turn, making carbon fiber from PPP fiber.
