Synthesis and Characterisation of PVP-AAm Hydrogels via Hybrid Process: Morphological, Physical, and Antibacterial Activity

Abstract

Hydrogels are three dimentional networks that constitute of either chemical or physical crosslinks. In this study, preparation of polyvinyl pyrolidone/polyacrylamide (PVA/PAAm) hydrogels exhibiting antibacterial property was demonstrated. Bio-derived α-bisabolol, d-limonene, and geraniol were utilized as antibacterial agents, whereas stabilization of PVA/PAAm hydrogels was achieved by using beta-cyclodextrin (β-CD). PVA/AAm polyblend solutions were polymerizided via UV-irradiation. Then freeze-thawing and anneal-swelling were respectively carried out. Once the morphological, physical properties of the resulting hydrogels was characterized antibacterial efficiency tests were also performed. In the end, it was demonstrated that PVP/PAAm/α-bisabolol and PVP/PAAm/geraniol hydrogels have good antibacterial properties against Escherichia coli with 9 mm zone inhibition.

Electrospun lavender essential oil-loaded polylactic acid nanofibrous mats for antioxidant applications

“…5. The wettability of a material surface is influenced by its chemical and geometrical structure [45,46]. Sufficient wettability is a desired biobased material characteristic when evaluating electrospun mats for food packaging and/or wound healing applications since it helps assist absorption of both moisture and exudates resulting from physicochemical changes in foods and wounds [36].…”
