Anticounterfeiting and photoluminescent cellulosic papers based on fluorescent acrylic copolymer nanoparticles containing coumarin

The gorgeous transformation of paper: from cellulose paper to inorganic paper to 2D paper materials with multifunctional properties

“…Nawaz et al 148 reviewed the methods for the chemical modification of cellulose-based materials such as 2D cellulose paper into smart fluorescent materials and their multifunctional applications, including anticounterfeiting, 146,149,150 chemical sensing, 151–153 and gas detection. 154 For example, Wang et al 146 constructed a superhydrophobic and photoluminescent cellulose-based paper for anticounterfeiting application by doping lanthanide-based nanocrystal/nanotitania in cellulose fibers.…”

Cellulosic fiber nanocomposite application review with zinc oxide antimicrobial agent nanoparticle: an opt for COVID-19 purpose

“…The former as being tested for its biomimetic skin with adequate mechanical properties containing nanocellulose or microcrystalline cellulose (MCC) for instance of 50 µm in size where the hydrogel was fabricated chemically via crosslinking and under cryogenically lower temperature of − 20 °C. Meanwhile, in the latter, a modified (Anju, 2021;Wang et al, 2022;Zhang et al, 2022a) Cellular/cellulose membrane, biomembrane, nanocellulose membrane, pollutant adsorbent Downstream processing industry (Alipour et al, 2020;Das et al, 2021;Perendija et al, 2021;Wang et al, 2020;Zhang et al, 2022b) Leaf fibers, sisal fibers, agrofibers, cellulose fibers Foams, polyester, PLA, biodegradable plastics (Bendourou et al, 2021;Guimarães et al, 2021;Jabber et al, 2021;Sathees Kumar et al, 2021;Siva et al, 2020) Modified/regenerated cotton cellulose Fabric industry (Khalili et al, 2021;Štular et al, 2021) Wood-cellulose fiber, graphitic cellufoil, SnS/ carbonized cellulose film Energy industry, battery industries (lithiumion battery), nanogenerators (Yi et al, 2021;Yuan et al, 2021;Zhang et al, 2021) Fluorescent smart materials Fluorescent application (Delavari et al, 2020;Kalita et al, 2015;Nawaz et al, 2021) Dietary fiber, bacterial cellulose Food industry (Lin et al, 2020;Revin et al, 2018;Zhu et al, 2022)…”

“…Nanogenerators and lithium-ion battery are two instances in energy industries applying cellulose film, foil or fiber for instance from wood-cellulose fiber, cellulose nanofibers, carbonized bacterial cellulose nanofibers with graphene nanoplatelets or with tin sulfide (SnS) nanosheets (Yi et al, 2021;Yuan et al, 2021;Zhang et al, 2021). Fluorescent smart materials support security via fluorescence emission (fluorescent latex nanoparticles, autofluorescent nanocrystals) in anticounterfeiting inks, security documents, sensor, manufacturing, biomedical, and pharmaceutical industries (Delavari et al, 2020;Kalita et al, 2015;Nawaz et al, 2021). In addition to all these, CFs are also fabricated as membrane or a pollutant removal adsorbent in downstream processing industries (Alipour et al, 2020;Das et al 2021;Perendija et al, 2021;Wang et al, 2020;Zhang et al, 2022b).…”

Preparation of Photoswitchable Polyacrylic Nanocomposite Fibers Containing Au Nanorods and Spiropyran: Optical and Plasmonic Properties

“…Among these, the spectacular properties of photoresponsive hybrid plasmonic systems have drawn much attention in optical and photonic devices because of their possibilities in reversible light−matter interactions. 9,19 In recent years, photosensitive molecules including photochromic (e.g., spiropyran, spironaphtoxazine, and azo derivatives) 20−23 and fluorescent molecules (e.g., coumarin, rhodamine, and fluorescein) 24,25 have become increasingly important. Spiropyrans, as a convenient category of the photochromic family, possess two isomeric structures (closed-ring spiropyran, SP, and open-ring merocyanine, MC) with different spectral features and dipole moments (SP, 4−6 D; MC, 14−18 D).…”
