Bicontinuous mesoporous carbon thin films via an order–order transition†
Abstract
Bicontinuous mesoporous carbon films are fabricated by cooperative self-assembly of phenolic resin and amphiphilic triblock copolymer via an order–order transition from cylinders to gyroid. The film morphology is strongly influenced by the details of processing, including age of the resol, resol : template ratio, and the solvent vapor annealing process.
