Abstract
The soft-template method is a powerful strategy for synthesizing mesoporous metal oxides (MMOs), offering high versatility that enables access to a wide range of compositions and nanostructures. Nevertheless, conventional approaches face fundamental limitations in two key stages. First, solvent-evaporation–driven block copolymer self-assembly inevitably requires toxic solvents. Moreover, homogeneous integration of 1D/2D nanomaterials into MMOs is challenging because of phase segregation and structural inhomogeneity. Thus, synergistic advantages of both nanomaterials and the mesostructure in MMOs are not expected. Second, high-temperature calcination is typically needed for template removal and metal oxide conversion from the precursors, which restricts a direct synthesis of MMOs on plastic substrates. Therefor, flexible energy storage devices based on MMOs could not be acheived. To overcome these two challenges, we introduce innovative condensation-induced self-assembly (CISA)1 where uniform dispersion of 1D/2D nanomaterials into MMOs is achived in an enviornemtally friend solvent such as acetone. Also, we utilize a synergistic effect of thermal activation and plasma, which enables a direct synthesis of various MMOs on a flexible polymer substrate.2
