- Abstract
A novel zirconia polyester nanocomposite is prepared using an in situ approach. Surface-functionalized zirconia nanoparticles are obtained by attaching 3-phosphonopropionic acid to the metal oxide. Neat and surface-covered metal oxide particles are incorporated at the beginning of the polyesterification reaction of isophthalic acid and neopentyl glycol resulting in zirconia/poly(neopentyl isophthalate) (PNI) nanocomposites. TEM shows that the dispersibility of the inorganic filler is improved by covering the zirconia surface with carboxylic acid groups. These results are verified by SAXS. Rheological measurements reveal that the viscosities are increasing compared to pristine PNI at particle loads of 10 wt% (neat zirconia) and 5 wt% (phosphonic-acid-capped zirconia), respectively.
