演講摘要：

Due to their light weight, flexibility, and biocompatibility, soft materials have attracted increasing attention. They are intrinsically similar to biological tissues and are promising as artificial organisms. However, most synthetic soft materials are structurally isotropic, while some biological tissues adopt anisotropic structures with hierarchically integrated units up to macroscopic size scales. As represented by muscles, nerves, and born, such structural anisotropy is critical for their superb functions.
To approach these functions by artificial systems, induction of structural anisotropy would be the first step. To this end, magnetic alignment is highly attractive, as it can cleanly and remotely align various non-spherical colloids. Importantly, magnetic fields can homogeneously penetrate deep into bulk materials, which is suitable for synthesizing anisotropic structures with high integrity. After magnetic alignment, in-situ crosslinking enables permanent fixation of the aligned structure.
Based on this strategy, we have recently developed several soft materials with an anisotropic structure that extends over a macroscopic size scale. In the resulting materials, the mutual interference between the colloids is maximized, so that they often exhibit special properties and functions. This talk will present recent examples of materials that are not only anisotropic, but also exhibit autonomy and polarity.
