Nanocomposite particles having water repellency and oil repellency or lipophilicity, a method for producing the same, column fillers and filters that can be used for oil-water separation using the nanocomposite particles, and water repellency on the surface of a substrate to be treated And a surface treatment agent capable of imparting oil repellency or lipophilicity, a surface treatment method, and a method for producing a nanocomposite particle dispersion. A nanocomposite particle contains a styrene-butadiene copolymer and a fluorine-containing compound represented by the formula (I). In formula (I), R 1 represents a group containing a fluoroalkyl group, R 2 represents an alkyl group or an alkoxyalkyl group, R 3 and R 4 each independently represent a hydrogen atom or a monovalent organic group, x is an integer of 1 to 100, and y is an integer of 0 to 100.
