Abstract
The manufacturing of sanitary and household furniture on a large scale with inherently
antimicrobial properties is an essential field of research. This work focuses on the synthesis of polymer
composites based on the unsaturated polyester of resin loaded with 5 wt.%-Triclosan produced by
a co-mixing approach on automated technological complex with a potential for broad applications.
According to findings, the polymer composite has a non-porous structure (surface area < 1.97 m2/g)
suitable for sanitary applications to reduce the growth of bacteria. The chemical composition confirmed
the presence of major elements, and the inclusion of Triclosan was quantitatively confirmed
by the appearance of chlorine on XRF (1.67 wt.%) and EDS (1.62 wt.%) analysis. Thermal analysis
showed the difference of 5 wt.% in weight loss, which confirms the loading of Triclosan into the polymer
matrix. The polymer composite completely inhibited the strains of S. aureus 6538-P, S. aureus 39,
S. epidermidis 12228, and Kl. Pneumoniae 10031 after 5-min contact time. The antimicrobial effects
against Kl. pneumoniae 700603, Ps. aeruginosa 9027 and Ps. aeruginosa TA2 strains were 92.7%, 85.8%
and 18.4%, respectively. The inhibition activity against C. albicans 10231 and C. albicans 2091 was
1.6% and 82.4%, respectively; while the clinical strain of C. albicans was inhibited by 92.2%. The
polymer composite loaded with 5 wt.%-Triclosan displayed a stability over the period that illustrates
the possibility of washing the composite surface.
