There is intense interest in making mechanically stable elastomers with properties resembling those of human muscles for use in soft robotics. Recently, a polydimethylsiloxane (PDMS) elastomer prepared without the use of cross-linking moieties from heterobifunctional PDMS macromonomers of intermediate molecular weight has been shown to exhibit surprising inherent softness and excellent stability upon both large deformation and swelling, in clear contradiction of classical rubber elasticity theories. In this work, this unexpected elasticity is shown to originate from concatenated rings.
人们对制造具有类似于人类肌肉特性的机械稳定弹性体用于软机器人技术有着浓厚的兴趣。最近，一种由中等分子量的异双功能聚二甲基硅氧烷（PDMS）大分子单体在不使用交联部分的情况下制备的聚二甲基硅氧烷（PDMS）弹性体，已被证明在大变形和溶胀时都表现出惊人的固有柔软性和出色的稳定性，这与经典橡胶弹性理论明显矛盾。在这项工作中，这种意想不到的弹性被证明源于连环环。
