The impact of fillers in the epoxy oligomer on the test culture of the marine ecosystem was
investigated. The content of additive—biocides—was selected based on the complex research using
STAT-GRAPHICS® Centurion XVI. The ecotoxicity of composite surfaces was determined in model
systems using methods which are standard in eco-microbiology. The microorganism was identified
by studying morphological, cultural, biochemical, and antigenic properties. Studies of the structure
and the microrelief of the surfaces of composite materials were conducted using scanning electron
microscopy (SEM) and X-ray energy dispersive spectroscopy. Based on comprehensive research, it
was established that the composition of oxytetracycline with content of q = 1.5 wt% and nanosilver
with a content of q = 0.075 wt% per 100 wt% of the DER-331 oligomer and 10 parts by the mass of
the TETA hardener ensures the formation of a porous nano-heterogeneous structure of the coating,
which leads to the acceleration of the release of silver ions from the surface of the polymer. The
rational content of the complex additives of biocides ensures adhesion to the cell wall of bacteria with
subsequent penetration into it and subsequent change to the cell membrane, its death, and, therefore,
the suppression of the fouling process of metal structures.
