. Due to its optical, chemical and electronic properties, graphene oxide (GO), among others subtypes of graphene-based materials, has been broadly studied over the past decade. Thanks to its contact-based antimicrobial activity GO represents a good candidate for the construction of materials with antimicrobial properties. Thus, GO's capability to interact with microbes delivers a prospect to improve textiles designed for usage as personal protective equipment. This paper presents the results concerning the obtain of the GO-impregnated SFM-1 polypropylene membrane, its morpho-structure and antimicrobial activity and adherence on two gram-negative bacteria (E. coli, S. thyphimurium), a gram-positive bacterium (S. aureus) and a yeast (C. albicans). The investigations on the GO-impregnated polypropylene diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) suggested the successful polypropylene impregnation with GO. The antibacterial tests have shown that all but one of the microorganisms (S. typhimurium) displayed to be susceptible to the antimicrobial activity of the GO material. Bacterial adhesion was also checked to simulate their affinity for the polypropylene surface immediately after impregnation, in this case the best results were observed on the S. aureus strains.
