Hygromorph composites are moisture-induced shape-changing materials that are increasingly studied to develop autonomously actuated deployable structures. The morphing mechanism is based on the high affinity for moisture and the hygroexpansive nature of at least one component, combined with a bilayer microstructure. Among available hygromorphs, those consisting of cellulosic or hydrogel material-based actuators trigger fast responses to moisture. Their stiffness however decreases significantly with the moisture content and that restricts their potential application as soft actuators. This work proposes a novel 4D printed multistimuli-responsive structural material based on conductive carbon reinforcements and combined with a moisture sensitive polymer. These 4D printed materials possess a microstructure that provides the capability of natural actuators like pine cones. The actuation of these functional materials could be either triggered passively by the variation of the ambient moisture, or by electroheating, with the latter leading to the control of the moisture content in initially wet samples via Joule effects. This new class of functional materials shows an increase of the actuation speed by a factor 10 compared to other existing hygromorphs with the same responsiveness. When the electrical heating is turned off, passive cooling and moisture driven actuation is triggered in a full reversible mode.

“…The majority of recent bioinspired structural or smart materials are based on the use of synthetic carbon fossil-based components, for which their life cycle impact is not considered in their design. This class of smart composites are used to convert environmental stimuli (like temperature) into a mechanical reversible deformation [3]. In this way, an actuation functionality is directly embedded in the microstructure of the material without using complex external devices [4].…”

Hygromorph biocomposites (HBC) possess moisture-induced actuation from bioinspired designs. The present work describes a large experimental and comprehensive database of the hygro-mechanical and bending actuation properties of flax/maleic anhydride grafted polypropylene (MAPP) HBC composites over a large range of moisture variation (10-90% RH) and water immersion. HBCs exhibit a promising responsiveness and reactivity over the whole relative humidity range (10-90% RH), with acceleration and increase of the actuation observed as soon as a 30% RH value is reached. The experimental data are compared to analogous results from an analytical model based on a modified Timoshenko theory, and a finite element model based on the use of classical laminate theory (CLT). We discuss the effects of the hygroscopic properties (β coefficient) and the design parameters (length/width and thickness ratios) of the composites on the actuation performance.

3D Printing has been recognized as a disruptive technology for future advanced manufacturing system. With a great potential to change everything from our daily lives to the global economy, significant advances in 3D printing technology have been made with respect to materials, printers and processes. In this context ,although similar to 3D Printing technology,4D printing technology adds the fourth dimension of time.4D printing allows a printed structure to change its form or function in time and response to stimuli such as pressure , temperature, wind, water and light. recently, rapid advances in printing process and materials development for 3D printing have allowed the printing of smart materials or multi-materials designed to change function or shape. The basic principle of 4D printing with multi material structure is to create precisely controlled localized internal stress with in a printed construct, which upon subsequent stress release can undergo further 3D shape shifting in a predictable manner In this review, we look into the main factors composing 4D printing technology such as smart materials and design. Finally we summarize the current and future applications of 4D printing.
