VEGA BAUDRIT, José; MARTIN MARTINEZ, José Miguel y CAMACHO ELIZONDO, Melissa. Influencia de las nanopartículas de sílice en polímeros termoplásticos. Mundo nano [online]. 2013, vol.6, n.11, pp.40-51. Epub 23-Jun-2021. ISSN 2448-5691. https://doi.org/10.22201/ceiich.24485691e.2013.11.50003.
In this work we have prepared silicas with different hydrophilicity to reduce the degree of interaction with the polyurethane and analyze the effect on the properties of the composites obtained.
A hydrophilic pyrogenic silica was incorporated in different polyurethane adhesives with different relation NCO/OH where the degree of phase separation is enhanced at all polyurethanes, indicating a potential interaction of the silanol groups of the silica by hydrogen bonding with the polymer. Therefore, there should be a variation in properties as polyurethanes response to the presence of the dispersed silica.
