“…For example, thermochromic materials can display substantial infrared emissivity changes because of thermally induced phase transitions but feature high operating temperatures, hysteresis during cycling, and structural characteristics that are difficult to control (8)(9)(10)(11)(12). In addition, infrared electrochromic devices have optical properties that can be altered with electrochemical redox reactions but struggle with precise spectral tunability and necessitate the use of inert noble metals in order to achieve functionality and stability (13)(14)(15)(16). Moreover, certain metamaterial-based systems can spatiotemporally modulate their emissivity through photogenerated carrier doping but use ultraviolet light for actuation, need elevated working tempera-tures for adequate contrast, and display long recovery times (17).…”

Materials and systems that statically reflect radiation in the infrared region of the electromagnetic spectrum underpin the performance of many entrenched technologies, including building insulation, energy-conserving windows, spacecraft components, electronics shielding, container packaging, protective clothing, and camouflage platforms. The development of their adaptive variants, in which the infrared-reflecting properties dynamically change in response to external stimuli, has emerged as an important unmet scientific challenge. By drawing inspiration from cephalopod skin, we developed adaptive infrared-reflecting platforms that feature a simple actuation mechanism, low working temperature, tunable spectral range, weak angular dependence, fast response, stability to repeated cycling, amenability to patterning and multiplexing, autonomous operation, robust mechanical properties, and straightforward manufacturability. Our findings may open opportunities for infrared camouflage and other technologies that regulate infrared radiation.

An electrochemical approach towards developing a lead(II) ion selective polymer is presented. A poly(aniline-co-3-aminobenzenesulfonic acid), P(Ani-co-3ABSA), membrane would be reconciled with the peculiarities of lead(II) ions by incorporating them. It seems that consecutive embedding/ejecting of lead(II) into-from the mass of P(Ani-co-3ABSA) coating, correspondingly templates the coating towards lead(II) ion. This method results in a highly selective sensor for the measurement of lead(II) ion. The optimal conditions for sensor operation were ascertained. The surface morphology of the freshly synthesized, templated and templated-preconcentrated P(Ani-co-3ABSA) membranes were explored by SEM. The interference effect on the voltammetric response with coexisting ions was also investigated. The developed sensor was applied for lead(II) determination by pre-concentration/differential pulseanodic stripping voltammetry in concentrations of 1.0 nM to 0.1 mM and by potentiometric method in concentrations of 10.0 nM to 1.0 mM.

“…The intrinsic synthesis-structure-electrochromic performance relations have also been investigated and determined. Among various electrochromic polymers, polyaniline has received intensive interest because of its low redox potentials, high electroactivity, and multiple color switching characteristic [6][7][8][9][10]. Likewise, several synthetic tactics have been explored and employed to enhance the electrochromic properties of polyaniline-type polymers.…”

Abstract. Electrochromic polymers have attracted much attention due to their potential applications in displays, smart windows, intelligent mirrors, and wearable devices. Here, a novel polyamic acid containing aniline pentamer with improved electrochromic properties and new functionalities was synthesized via oxidative coupling polymerization, followed by postpolymerization of tetraaniline, polyhedral oligomeric silsesquioxane, and fluorene, respectively. With the introduction of tetraaniline pendants, the resultant polymer exhibits improved electrochromic performance with high optical contrast value and rapid switching rate, because of the high content of electrochromic units in the polymeric structure. The polyamic acid functionalized with polyhedral oligomeric silsesquioxane, demonstrates a great enhancement of switching rate in the electrochromism, due to the rapid electrolyte migration through polymer film under electrochemical potentials. In addition, a new electrofluorochromic feature is easily achieved through the introduction of fluorescent fluorene groups into the polymeric architecture.
