Effect of hydrothermally synthesized titanium nanotubes on the behaviour of polypropylene for antimicrobial applications

Abstract: Artículo de publicación ISITiO2 nanotubes (TiO2-Ntbs) synthesized by a hydrothermal method were used as filler to prepare polypropylene (PP) composites by melt blending. Their structural properties as well as their biocidal potential were studied. Nanotubes were used either as-synthesized or organically modified with hexadecyltrimethoxysilane (Mod-TiO2). These nanoparticles form secondary structures with sizes around 100 nm that are well dispersed in the polymer matrix, but not homogeneously because agglomerat… Show more

“…The T10 increased 9 ºC for LDPE/ZnO with 8 wt.% of ZnO compared to LDPE, regardless of the nanoparticle modifications. These results suggest that the nanoparticles may provide a better insulator and mass transport barrier for the volatile products generated during their decomposition in the LDPE [2,[17][18][19].…”

“…The percent of crystallinity was calculated using the enthalpy of fusion of an ideal polyethylene with 100% crystallinity ( : 289 J·g −1 ) [ 39 ]. The percent crystallinity of the nanocomposites was obtained from Equation (1), where x is the percent of nanoparticles in the polymer [ 40 ]. …”

“…Then, 0.2 mL of each dilution was plated in duplicate on trypticase soy agar plates and incubated at 37 °C for 24 h. After incubation, the number of colonies in the Petri dishes was counted and, in this way, the percentage of inhibition of microorganisms in each sample was determined compared to the corresponding control. The percent reduction in the colonies was calculated using the following equation (Equation (2)), which relates the number of colonies from the neat polymer to the number of colonies from the nanocomposites [ 40 ]. …”

“…Biofouling is ascribed to the adsorption and accumulation of proteins and micro‐ and macroorganisms on surfaces . Biofouling causes problems in medical implants, surgical devices, biosensors, food processing and packing, and marine ships . Biofouling starts with adsorption of proteins to create a conditioning film on the substrates, followed by colonization by adherent bacteria.…”
