Synthesis, photodegradable and antibacterial properties of polystyrene-cinnamaldehyde copolymer film

Bioinspired and eco-friendly high efficacy cinnamaldehyde antibacterial surfaces

“…44 Many of the reported cinnamaldehyde-based antibacterial materials and surfaces involve the blending of cinnamaldehyde with a polymer (either as a melt or in solution) followed by casting into a film. Some of the polymers used include: polyvinyl alcohol, 45 polypropylene, 46 polystyrene, 47 cellulose, 48 and chitosan. 49 Such cinnamaldehyde-containing films are effective at stopping bacterial or mould growth on, for example, various foodstuffs-including beef, 45 chicken and ham, 50 vegetables (radish, broccoli, and alfalfa) sprouts, 51 and bakery products.…”

Optical, mechanical, structural, and antimicrobial properties of tamarind kernel powder, halloysite, and cinnamaldehyde nanocomposite films

“…The CND incorporated films demonstrated peaks at the wavenumber region analogous to TKP/HS film. However, CND‐loaded films confirmed higher intensity peaks as compared with TKP/HS film at ~677 cm −1 , which indicated the successful incorporation of CND into the film matrix (Chen et al, 2016; Nayanathara et al, 2018; Zhang et al, 2020). The signal at ~677 cm −1 was because of the out of plane CH = CH bending corresponding to the phenyl group of CND (Chen et al, 2016; Srisa & Harnkarnsujarit, 2020).…”

Defect engineering and spilt-over hydrogen in Pt/(WO3–TH2) for selective hydrogenation of CO bonds

“…Even after He flushing at 100 1C for 180 min, the chemical absorption of the CQO group (at 1680 cm À1 ) can still be observed clearly. 30,59 Based on the semi-quantitative analysis of in situ DRIFTS, it is reasonable to conclude that the number of chemically absorbed CAL molecules on Pt/(WO 3 -300H 2 ) was higher than that on Pt/ WO 3 . Evidently, the defects (oxygen vacancies) on the catalysts are beneficial to the adsorption and activation of the CQO bond of CAL.…”
