Ionic electromechanically active capacitive laminates are a type of smart material that move in response to electrical stimulation. Due to the soft, compliant and biomimetic nature of this deformation, actuators made of the laminate have received increasing interest in soft robotics and (bio)medical applications. However, methods to easily fabricate the active material in large (even industrial) quantities and with a high batch-to-batch and within-batch repeatability are needed to transfer the knowledge from laboratory to industry. This protocol describes a simple, industrially scalable and reproducible method for the fabrication of ionic carbon-based electromechanically active capacitive laminates and the preparation of actuators made thereof. The inclusion of a passive and chemically inert (insoluble) middle layer (e.g., a textile-reinforced polymer network or microporous Teflon) distinguishes the method from others. The protocol is divided into five steps: membrane preparation, electrode preparation, current collector attachment, cutting and shaping, and actuation. Following the protocol results in an active material that can, for example, compliantly grasp and hold a randomly shaped object as demonstrated in the article.
离子机电活性电容性层压板是一种智能材料，可响应电刺激而移动。由于这种变形具有柔软、柔顺和仿生的特性，由层压板制成的致动器在软机器人技术和（生物）医学应用中受到越来越多的关注。然而，需要能够轻松大量（甚至工业化规模）制造活性材料，并且具有高批次间和批次内重复性的方法，才能将实验室知识转化为工业应用。本方案描述了一种用于制造离子碳基机电活性电容性层压板及其制成的致动器的简单、工业可扩展且可重复的方法。包含一个无源且化学惰性（不溶性）的中间层（例如，纺织增强聚合物网络或微孔特氟龙）使该方法有别于其他方法。该方案分为五个步骤：膜制备、电极制备、集流体附着、切割和成型以及驱动。按照该方案操作可得到一种活性材料，例如，如本文所示，它能够柔顺地抓取和握住任意形状的物体。
