In our continuing search for new polymer composites with antimicrobial activity, we observed that even unmodified epoxy resins exhibit significant activity. Considering their widespread use as starting materials the realization of multifunctional nanocomposites excellent chemical and mechanical properties, it was deemed relevant to uncover these unexpected properties can lead novel applications. fact, in places where contact human activities makes working surfaces susceptible microbial contamination, thus jeopardizing sterility environment, biological activity opens way successful application minimizing healthcare-associated infections. To this end, three commercial widely used (DGEBA/Elan-TechW 152LR, 1; EPIKOTETM Resin MGS®/EPIKURETM RIM H 235, 2 MC152/EW101, 3) have been investigated determine antibacterial antiviral After 24 h, according ISO 22196:2011, 1 showed a high efficacy (R value > 6.0 log reduction) against Staphylococcus aureus Escherichia coli. 2, prepared ratio epoxy/hardener indicated by supplier (sample 2a) 10% w/w hardener excess 2b), exhibited an intriguing virucidal Herpes Simplex Virus type-1 Human Coronavirus type V-OC43 surrogate SARS-CoV-2.
