Microphase separation of block copolymers in nanometer-sized periodic domains has opened a new synthetic route for nanometer scale functional materials. Herein, we present that block copolymer assembly route generated functional nanoporous materials for energy devices, such as fuel cell, solar cell and lithium ion batteries. The direct synthesis of highly crystalline mesoporous transition-metal oxides that are thermally stable and well ordered still constitutes a major challenge. Although various soft- and hard-templating approaches have been developed in the past, they usually suffer from multiple, tedious steps and often result in poor structure control. For many applications including power generation and energy conversion, high crystallinity and controlled mesopores are a prerequisite. To this end, we developed combined assembly of soft and hard chemistries (CASH) method using sp2 carbon containing poly(isoprene-b-ethylene oxide) as a soft structure directing agent. |
