Abstract
Provided is a metal-oxide nanofiller including at least two graft chains, at least one of the chains being hydrophilic and the other being a hydrophobic chain compatible with fluorinated polymers. The hydrophobic chain is an oligomer, the weight-average molar mass Mw of which is between 300 and 20,000 g/mol−1. Also provided is a non-stick coating comprising such a filler, as well as to a culinary article provided with such a coating.
