Abstract: The present disclosure is directed to methods of forming polyimide gels. The methods generally include forming a polyamic acid and dehydrating the polyamic acid with a dehydrating agent in the presence of water. The resulting polyimide gels may be converted to polyimide or carbon xerogels or aerogels. The methods are advantageous in providing rapid or even instantaneous gelation, which may be particularly useful in formation of beads comprising the polyimide gels. Polyimide or carbon gel materials prepared according to the disclosed method are suitable for use in environments containing electrochemical reactions, for example as an electrode material within a lithium-ion battery.

Abstract: A method for making polyethylene aerogels, including high molecular weight aerogels, commences by in a hydrocarbon solvent (e.g., toluene or benzene) in which polyethylene is insoluble at room temperature, adding polyethylene to the solvent heated to a temperature at which said polyethylene is soluble to form a reaction mixture. A free-radical catalyst is added to the reaction mixture and the reaction mixture is held until the desired gelation of the polyethylene has been achieved. The reaction mixture is cooled to about room temperature; and the hydrocarbon solvent is replaced with a gas (e.g., CO2 or air) to form the polyethylene aerogel. Optionally, the cooled reaction mixture can be contacted with an anti-solvent for polyethylene to replace the hydrocarbon solvent with the anti-solvent. Silica aerogel particles can be encapsulated in polyethylene aerogel by adding the particles to the polyethylene gelation reaction mixture.

Abstract: The present invention relates to a polymer substrate that contains polycrystalline pores formed on a surface thereof and a method of preparing the same by a surface treatment. The polymer of the present invention contains, on its surface, pores with a polycrystalline structure, and, thus, it exhibits hydrophobicity that accounts for a high fouling resistance. Not only that, the hydrophobicity provides the polymer substrate with the ability for mechanical adhesion in the formation of an adhesive interface, resulting in an excellent adhesive strength. Also, the method of surface treatment to prepare such a substrate is advantageous in that it can treat a large area of a surface economically while not using substances that are harmful to the human body and environment.
