Abstract

Bottlebrush block copolymers (BBCPs) offer compelling advantages for self-assembly including rapid ordering dynamics and access to domain sizes in excess of 200 nm. Cooperative assembly of BBCPs with additives including nanoparticles, carbon precursors and metal oxide precursors can be readily accomplished at high additive loadings by introducing strong specific interactions between at least one segment of the BBCP and the additive. The resulting well-ordered composite materials can subsequently be patterned at the device level using nanoimprint lithography and finally converted to the desired hierarchical device structure by heating, rapid thermal annealing or pulsed flashlamp processing. Applications in high energy and power density supercapacitors, battery anodes, optical films, and metamaterials will be discussed.
