Summary: As a new type of smart device, soft actuators have gained attention for their simple structure, fast response, and wide range of applications. However, most soft actuators are driven by a single stimulus and lack versatile functionalities. To address this issue, a multi-functional and integrated actuator based on PANI@CNT-CNF composites is proposed. This actuator can respond to humidity and light, making it suitable for biomimetic applications and has the ability of energy storage. Furthermore, an integrated actuator that combines actuation and energy storage is designed and demonstrated to have potential for applications in smart devices.

Summary: MXene, a two-dimensional transition metal carbide, nitrides, and/or carbonitrides, shows great potential in various research fields due to its excellent conductivity, hydrophilicity, and abundant surface functional groups. However, challenges in aggregation and low stability greatly limit its applicability. MXenes can be synthesized through techniques such as exfoliation of MAX phases assisted by HF and nonHF materials, and bottom-up approaches utilizing vapor deposition and templating methods. MXene-based heterostructure composites have been investigated as potential nanomaterials for energy storage, and this article provides an overview of MXene synthesis and current developments in MXene-based heterostructure composites for electrochemical energy storage devices. Challenges and difficulties in the future design of MXene-based heterostructure composites are also discussed.
