AB  - The study reports an effluent-free, green process for the production of materials with favorable antibiofilm properties by cellulose acetate grafting with quaternary ammonium compounds in supercritical carbon dioxide. Two quaternary ammonium compounds, N-(2-Hydroxyethyl)-N,N-dimethylundecan-1-aminium Bromide and N-(11-Hydroxyundecanyl-N,N-dimethyltetradecan- 1-aminium Bromide, were synthesized and chemically attached to cellulose acetate via hexamethylene diisocyanate as a linker under the conditions of 30 MPa and 70 °C. The polymer modification occurred in its whole volume. The chemical conversion led to a decrease in the degree of crystallinity and the appearance of a rugged polymer surface. However, the cross-section imaging of the newly obtained materials revealed a compact polymer structure. The functionalized materials acquired hydrophobic properties. Microbiological tests showed the impossibility of Staphylococcus aureus ATCC 29213, Methicillin-resistant Staphylococcus aureus ATCC 43300, Escherichia coli ATCC 10536, and Salmonella Enteritidis ATCC 13076 attachment to the material obtained by the cellulose acetate grafting procedure with N-(11-Hydroxyundecanyl-N,N-dimethyltetradecan- 1-aminium Bromide.

AB  - There is an urgency to develop novel materials capable of preventing the adherence of microorganisms to
their surface. Such materials with antibiofilm properties are needed in hospitals and public places, animal
farms and veterinary hospitals, and biofouling prevention. Biofouling is the phenomenon of adhesion and
the growth of microorganisms on surfaces in contact with water. It poses a significant problem for filtration
processes, water treatment units, bioreactors, and ships performance (marine biofouling). High-pressure
techniques such as supercritical solvent impregnation and grafting in the supercritical phase allow for the
modification of a solid matrix throughout the whole volume and production of materials of unique
properties in an environmentally friendly way. Grafting involves the chemical attachment of an active
compound to a solid matrix, ensuring its long-lasting properties. Grafting in supercritical carbon dioxide
(scCO2) has been reported as an efficient tool in the production of materials with antibacterial1
, and recently
also antibiofilm properties2
. This study aims to investigate the potential of cellulose acetate (CA) grafting
with quaternary ammonium compounds (QAC) for acquiring antibiofilm properties. Two QAC were
synthesized, and the grafting conditions were investigated. The grafting was performed via hexamethylene
diisocyanate (HDI) as a linker1
. Obtained materials were analyzed using FTIR, SEM and Ion microscopy,
DSC analyses, contact angle measurements, and standardized microbiological procedures to evaluate
antibiofilm properties.
