Bacterial-growth inhibiting properties of multilayers formed with modified polyvinylamine

Water-stable cellulose fiber foam with antimicrobial properties for bio based low-density materials

“…Polyvinylamine (PVAm) is a cationic polymer that is used in the paper industry to increase the strength of paper (BASF 2010). PVAm has good antibacterial properties, due to its primary amine groups, and has been used in several studies to create contact-active antibacterial cellulose using Layer-by-Layer (LbL) modification (Chen et al 2017;Henschen et al 2016;Illergård et al 2011Illergård et al , 2015Westman et al 2009). Chitosan is a cationic polysaccharide derived from naturally occurring chitin through deacetylation, and it is used in cosmetic, food and pharmaceutical products because of its antimicrobial properties (Rinaudo 2006;Sebti et al 2005).…”

Influence of alkyl chain length on the surface activity of antibacterial polymers derived from ROMP

“…Several reports have shown that charge is another key parameter to examine the antibacterial surfaces [21,24,37]. Therefore, we studied and compared the antibacterial activity with contact angle and cationic charge densities of the polymers.…”

Cellulose-based water purification using paper filters modified with polyelectrolyte multilayers to remove bacteria from water through electrostatic interactions

“…[38][39][40] Cellulose fibres treated with multilayers of cationic polyvinyl amine (PVAm) and anionic polyacrylic acid (PAA) have previously been shown to adsorb more than 99.9% of E. coli in a fibre suspension without leaching any biocides. [41][42][43] The effect was, however, notably reduced when turbid water samples were used, due to a decreased contact between the LbL-modified fibres and the bacteria, and a filtration approach is therefore desired.…”
