Back Cover: In article number 2000765 by San H. Thang, Anchao Feng, Zhao Wang, and co-workers, a series of well-defi ned CO2-responsive statistical, gradient and block copolymer nano-objects are synthesized through batch, semi-batch and stepwise reversible addition-fragmentation chain transfer (RAFT) polymerization. In aqueous solution, the copolymers can self-assemble into various aggregates before CO2 stimulus. Upon bubbling CO2, the gradient copolymers prefer to form nanosheet-like structures, while the block and statistical copolymers with similar molar mass can only form larger vesicles with thinner membrane thickness or disassemble.
