Developing adsorbent materials for the efficient removal of multiple organic pollutants in water is importance technological significance. In present work, a kind conjugated microporous polymer (CMP) with hollow sphere structure was constructed by applying SiO2 nanoparticles as template and 1,3,5-triethynylbenzene (TEB) 2,7-dibromocarbazole (27-DBCZ) building blocks via Sonogashira–Hagihara cross-coupling reaction. order to further improve dispersibility as-resulting CMPs water, hydrophilic (H–S–CMPs) were obtained sulfonation modification.

Color changing stimuli sensitive polymeric materials, toward varying heat (thermochromic) or voltage (electrochromic) conditions, have gained topical scientific interest owing to intrinsically valuable property-performance profiles. Research advancements on these exceptional categories of materials led novel designs high-performance color-shifting matrices reinforced with graphene nanoadditives. Accordingly, the current mutinous field review documents technical worth thermochromic polymer/graphene nanocomposites and electrochromic casing notable fundamental/structural aspects, fabrication tactics, physical attributes especially related coloration/decoloration applied heat/current stimuli. For nanocomposites, thermoplastic (poly(ethylene terephthalate), poly(dimethyl siloxane), cellulose, etc.) for nanomaterials conjugated (polyaniline, polythiophene, poly(3,4-ethylenedioxythiophene), derivatives) seemed be finest choice reinforcement. In view microstructural, thermal/mechanical stability, phase/glass transition temperatures, critical solution temperature, optical/transmittance, current–voltage, heat/stimuli sensitivity/efficiency; color aptitudes been discussed here. As per our analysis, literature hitherto divulged promising next-generation applications smart windows, thermo-sensor/e-sensors, e-textiles, energy devices, defense camouflage. Nevertheless, future commercial scale production/utilization advanced graphene-based automated transitioning hybrids demand cutting-edge design innovations, controlled/optimized synthesis strategies, focused investigations underlying mechanisms as well structure-property-performance challenges/aspects.
