目前调节弹性体材料的机械性能的方法主要是基于不同聚合物、溶剂和填料的探索性混合，这在应用中是不灵活的，并且在性能控制中是不精确的。在这里，我们概述了一种新的材料设计方法，利用独立控制的结构参数的明确分子代码来编程机械“表型”的大变化。这种按结构设计的方法在弹性体的分子结构和物理行为之间产生了一组普遍的相关性。反过来，这将导致新的无溶剂材料，这些材料密切模仿生物组织的机械行为，从软脂肪组织到坚硬的皮肤，并从根本上改变高影响力技术，如软机器人，可穿戴电子产品和生物医学设备。
The current approach to regulating mechanical properties of elastomeric materials is predominately based on the exploratory mixing of different polymers, solvents, and fillers-which is both inflexible in application and imprecise in property control. Here we overview a new materials design approach that harnesses well-defined molecular codes of independently controlled architectural parameters to program grand variation of mechanical "phenotypes". This design-by-iarchitecture approach generates a set of universal correlations between the molecular architecture and the physical behavior of elastomers. In turn, this will lead to novel solvent-free materials that closely mimic the mechanical behavior of biological tissues, ranging from soft fat tissue to firm skin, and fundamentally change high-impact technologies such as soft robotics, wearable electronics, and biomedical devices.
