“…With the development of space exploration, shape memory materials (SMM) with light weight, large deformation, and high recovery rate have been applied in deployable structures of wings, satellites, and spacecraft. In addition to the above-mentioned advantages, PIs, as a special material suitable for the space field, have a certain basis of shape memory efficiency [ 175 , 176 , 177 , 178 ]. Their large storage modulus difference between the high elastic and glass states endows them with a high shape fixing rate.…”

Polyimide (PI) is one of the most dominant engineering plastics with excellent thermal, mechanical, chemical stability and dielectric performance. Further improving the versatility of PIs is of great significance, broadening their application prospects. Thus, integrating functional nanofillers can finely tune the individual characteristic to a certain extent as required by the function. Integrating the two complementary benefits, PI-based composites strongly expand applications, such as aerospace, microelectronic devices, separation membranes, catalysis, and sensors. Here, from the perspective of system science, the recent studies of PI-based composites for molecular design, manufacturing process, combination methods, and the relevant applications are reviewed, more relevantly on the mechanism underlying the phenomena. Additionally, a systematic summary of the current challenges and further directions for PI nanocomposites is presented. Hence, the review will pave the way for future studies.

“…They are expected to replace solid indium tin oxide to manufacture various ultra-thin flexible 3D optoelectronic devices and expand the application of flexible transparent electric actuators. Yang et al devised a technique to manufacture recyclable thermosetting SMPI of a high standard without the need for a catalyst, achieved by combining amine-terminated bisimide (ATBI) and 1,3,5-triformylbenzene (TFB), providing a fresh avenue for the production of "smart" and recyclable polymer materials [172] .…”

Polyimide (PI), as an advanced polymer material, possesses the intrinsic merits of excellent resistance to extreme temperatures, good dielectric properties, flame resistance, strong processibility, biocompatibility, and flexibility. The outstanding performances of flexible PI have led to a wide range of applications in aerospace, medical, intelligent electronic devices, energy storage devices, and more. Notably, due to the swift progress of various flexible and soft devices, flexible PI has become ubiquitous in the form of thin films, fibers, and foam and gradually plays an indispensable role in all sorts of those devices. This review mainly focuses on the current advances in the usage of flexible PI for barrier, sensor, and functional purposes. Firstly, the key features of various methods for synthesizing and processing PI, as well as the relationship with their respective applications, are summarized. Secondly, to give readers a comprehensive view of the various applications of flexible PI materials, the applications are broken down into three categories: flexible barrier applications, flexible sensing applications, and flexible function applications, and the current research of each application is introduced in detail. Finally, a summary of the challenges and possible solutions in some flexible applications is present.

“…The fast-developing technology in shape memory alloy (SMA) actuators for microdevices integrates SMA materials as composites on an elastic substrate. The main advantage of SMA composites in the form of thin films was large surface area-to-volume ratio, which cause fast heating and cooling responses due to low thermal mass (Narayane D et al, 2022). The flexible substrate generates bias force during the cooling cycle and induces the cyclic actuation by producing required stress, also which can be pre-strained in different shapes based on the requirements (Kishi et al, 2013).…”

The recent development in smart material-based actuators are composite structures of thin film integrated SMA/PI bimorph in the view of actuator cum sensing in electromechanical systems for medical, robotics, and aerospace application. The purpose of the present work on integrated SMA/PI bimorph is to reveal their ability to perform as actuators and sensors and study on control characteristics for soft robotic, positioning, and valve applications. Vide this research paper, the SMA bimorph actuator [thin film SMA (CuAlNi)/polyimide (Kapton) bimorph] is used as actuator cum sensor for position control. Proposed a Proportional Derivative combined Variable Structure Controller (PD-VSC) to control the displacement by Joule heating actuation in two ways, which are sensor-based control and self-sensing control. From the control characteristics in from of tracking and disturbance rejection, it is concluded that the integrated CuAlNi/Kapton bimorph can be successfully implemented for soft robotic, positioning, and valve applications.
