“…Moreover, it is worth pointing out that the characteristic metakaolin Si–O–Al band at 810 cm −1 due to the six-coordinated Al(VI)–O stretching vibration, disappears in the geopolymer indicating a complete geopolymerization reaction [44]. Finally, the signal at about 460 cm −1 is due to Si–O bending vibration [44,45,46,47,48,49,50,51,52]. …”

Synthesis and Characterization of Novel Epoxy Geopolymer Hybrid Composites

Abstract:The preparation and the characterization of novel geopolymer-based hybrid composites are reported. These materials have been prepared through an innovative synthetic approach, based on a co-reticulation in mild conditions of commercial epoxy based organic resins and a metakaolin-based geopolymer inorganic matrix. This synthetic strategy allows the obtainment of a homogeneous dispersion of the organic particles in the inorganic matrix, up to 25% in weight of the resin. The materials obtained present significantly enhanced compressive strengths and toughness with respect to the neat geopolymer, suggesting their wide utilization for structural applications. A preliminary characterization of the porous materials obtained by removing the organic phase from the hybrid composites by means of heat treatments is also reported. Possible applications of these materials in the field of water purification, filtration, or as lightweight insulating materials are envisaged.

“…[1][2][3][4] The inhibitory and bacterial effects of the silver salts are well known since antiquity, i.e., some compounds of silver are effective against burns, severe chronic osteomyelitis, urinary tract infections, and central venous catheter infections. [5][6][7][8][9][10] However, in order to reduce the total silver dose and then to improve its biocompatibility, several investigations are currently developing nanostructured materials containing silver nanoparticles that present higher efficiency due to their large specific surface area and their small size, which allows them to interact closely with the cell membranes of the microorganisms. [11,12] The antimicrobial properties of silver nanoparticles have been largely studied and several mechanisms to explain their biocide activity have been proposed.…”

Silver doped glass powders have been obtained starting from vitellinate/nAg and montmorillonite/nAg. These powders have shown a high biocide activity against the three different types of microorganisms studied: Escherichia coli (gram‐negative bacteria), Micrococcus luteus (gram‐positive‐bacteria), and Issatchenkia orientalis (yeast). It was found that these glasses keep constant the silver concentration even below the cytotoxic limit. Therefore we interpret that silver doped glasses play the role of dosing devices.
