Smart photochromic and fluorescent products can respond to an external stimulus by changing their colour and emission spectra with light. Here, we developed a simple formulation of an organic–inorganic nanocomposite photoluminescent cellulose acetate (CA) film based on immobilization of a lanthanide‐doped pigment. Strontium aluminium oxide pigment doped with Eu2+ and Dy3+ (SAOED) exhibits an optimal excitation wavelength at 365 nm. For better fabrication of the multifunctional colourless pigment–cellulose acetate composites (CA–SAOED), the lanthanide‐doped colourant must be well‐dispersed physically without agglomeration. The fabricated photoluminescence cellulose film exhibited an excitation peak at 436 nm and two fluorescence peaks at 494 and 524 nm. The findings revealed that the originated nanocomposite films demonstrated improved superhydrophobic activity, high ultraviolet light protection and enhanced antibacterial activity without adversely influencing its native physico‐mechanical characteristics. The films demonstrated fast and reversible photochromic responsiveness without fatigue during ultraviolet light irradiation.

“…The activity recorded by the films also agrees with many studies on benzoxazine incorporated compounds. Several benzoxazine‐derivatives reported in several studies show potentials as antimicrobial and antibacterial compounds with significant results against pathogens [64–70] . The antifouling potential of polybenzoxazine modified compound has been reported by Lu, [71] with significant bactericidal and algicidal effects.…”

Fouling is an industrial problem that affects the maritime sector, and it has caused damages to equipment and vessels used in this industry. This research focuses on the synthesis of a novel arylidene‐based benzoxazine compound (HBC) and its use as a modifier for cellulose acetate (CA) matrix to form film samples and the investigation of their antifouling efficacy. The HBC compound was synthesized from a bis(arylidene)cyclopentanone diol compound and characterized appropriately using Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopic methods, respectively. Different weight ratios: 0, 10, 20, 30, and 40 %w/w of HBC to CA were mixed to give the films; CA‐0, CA‐10, CA‐20, CA‐30, and CA‐40, respectively. The fabricated films were characterized by FTIR analysis, and their morphology was examined by scanning electron microscopy (SEM). The thermal stability of the films was also studied using thermal gravimetric analysis (TGA), while the antifouling performance of the films was tested against strains of natural, biofilm‐forming bacteria isolated from artificial nets submerged in the Red Sea. Biofilm inhibitory test and bactericidal assay were conducted on the fabricated film materials using well established standard methods. The results of this investigation indicate that the HBC modified CA films contain relevant bioactive molecules that can inhibit primary colonizers in biofouling formation and will make a good antifouling coating film candidate. The CA‐40 revealed an inhibitory activity of 37 % and a bacterial killing efficacy of 87 %.

“…In recent decades, surface functionalization has been proven particularly effective in realizing unique textiles with desired properties such as self-cleaning, antibacterial, antifungal, fl ame retardancy, ultraviolet blocking and superhydrophobic [1][2][3][4][5][6]. In view of the close relationship with our daily life, the self-cleaning and antibacterial textiles are especially attractive.…”

This study discusses the effect of corona pretreatment and subsequent loading of titanium dioxide nanoparticles on self-cleaning and antibacterial properties of cellulosic fabric. The corona-pretreated cellulosic fabrics were characterized by field emission scanning electron microscopy, and X-ray mapping techniques revealed that layers of the titania deposited on cellulose fibers were more uniform than the sample without pre-corona treatment. The self-cleaning property of treated fabrics was evaluated through discoloring dye stain under sunlight irradiation. The antibacterial activities of the samples against two common pathogenic bacteria including Escherichia coli and Staphylococcus aureus were also assessed. The results indicated that self-cleaning and antibacterial properties of the corona-pretreated fabrics were superior compared to the sample treated with TiO2 alone. Moreover, using corona pretreatment leads to samples with good washing fastness.
