“…A comparison between the tensile strength of poly(lactic acid) and thermochromic bioplastic composite filaments revealed that as the amount of red and yellow thermochromic masterbatch increased in the composite bioplastic filaments, the tensile strength slightly decreased. This reduction in tensile strength can be attributed to the inhomogeneity of thermochromic powders within the poly(lactic acid) matrix 39 . With an increasing amount of masterbatch, the level of inhomogeneity also rises, leading to a decline in tensile strength.…”

This research aimed to produce thermochromic composite filaments by utilizing poly(lactic acid) (PLA) as a matrix and two distinct thermochromic additives (red and yellow colors). To produce thermochromic composite filaments with ratios ranging from 10 to 40 phr, different quantities of a thermochromic masterbatch were integrated into the PLA matrix through an extrusion process. The physical, mechanical, thermal properties, and thermochromic behavior of the composite filaments were further examined. The results indicated that the thermochromic additives had minimal impact on thermal and mechanical properties, while also revealing a two‐phase separation between the smooth matrix and the spherical particle additives in the thermochromic composite filaments. Moreover, the analysis of thermochromic behavior revealed that an increase in the ratio of thermochromic masterbatches led to more pronounced coloration and clearer color changes, especially with red and yellow thermochromics indicating temperature variations below 22°C and over 65°C, respectively. The sample containing 40 phr exhibited the most intense color and noticeable color change. Furthermore, these thermochromic composite filaments can be utilized to 3D print various prototype products.Highlights Thermochromic bioplastic composite filaments for 3D printing were successfully prepared. The thermochromic behavior analysis unveiled vivid coloration with distinct and more pronounced color changes.

Polyaniline (PANI) can achieve reversible optical modulation in visible and infrared (IR) bands under the action of voltage. However, PANI‐based electrochromic devices cannot cope with the dual detection of visible and IR light to realize the transmission of information due to the linkage restriction between the spectral modulation in the visible and IR region. Here, IR low‐absorptive inorganic pigments as colorants and IR high‐transparent polymer as a binder are utilized to prepare colored films with high transparency. A camouflage layer against visible light detection is constructed on the surface of IR electrochromic devices, and the information transmission is realized in the IR band by controlling the thermal radiation characteristics. Furthermore, thermochromic microcapsules (TMs) that change color under external thermal stimuli are introduced to fabricate a thermochromic and IR transparent functional layer, which is attached to the surface of IR electrochromic devices and endows the devices with separate spectral modulation ability in the visible and IR region. Multicolored displays are fabricated by arraying various devices. Moreover, visual patterns are prepared on the surface of IR electrochromic devices by dispensing technology. This configuration endows the device with a promising potential for anti‐counterfeiting, optical security, and related applications.
