Abstract
The present application is directed to methods for solvent-free preparation of polymers and their subsequent processing into activated carbon materials. These methods unexpectedly demonstrate ability to tune pore structure in the polymer gel and carbon produced there from, while also providing distinct advantages over the current art.
Claims17
A method for preparing a polymer, comprising physically blending a mixture of particles comprising polymer precursors and aging the mixture at a temperature and for a time sufficient for the polymer precursors to react with each other and form a polymer gel, and wherein the mixture comprises less than 10% solvent by weight, and the polymer precursors are monomers.
A method for preparing a polymer, comprising physically blending a mixture of particles comprising polymer precursors and aging the mixture at a temperature and for a time sufficient for the polymer precursors to react with each other and form a polymer gel, and wherein the mixture comprises less than 10% solvent by weight, and the polymer precursors are monomers comprising hexamethylenetetramine and bisphenol A present at a mole ratio between 0.05:1 to 5:1, respectively.
