Abstract
The rich phase behavior of block copolymers (BCPs) has drawn great attention in recent years. However, the double diamond (DD) phase is rarely obtained because of the competition between the minimization of interfacial energy and packing frustration. Here, a rod-coil BCP containing mesogen-jacketed liquid crystalline polymer is designed to acquire ordered bicontinuous network nanostructures. The reduction of internal energy originating from the orientational interaction among the rod blocks can compensate for the free energy penalty of packing frustration to stabilize the DD structure. The resulting BCP can also experience lamellae-to-DD and double gyroid-to-lamellae transitions by changing the annealing temperature. These results make the rod-coil BCP an excellent candidate for the self-assembly of ordered network structures, demonstrating great potential in nanopatterning and metamaterials.
期刊介绍:
Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985.
CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
