Abstract: The invention relates to composite particles, coatings, and coated articles. An article is provided at least partially covered with a coating defining a slippery surface. The coating comprises a layer of particulate material bound to the article and a substantially immobilised lubricant at least partially covering and penetrating into the layer of composite particulate material. The composite particulate material comprises a carrier particle at least partially coated with a hydrophobic material. A further article is provided at least partially covered with a coating comprising a layer of the composite particulate material bound to said article. This is useful in preparation of the article having a coating defining a slippery surface. Methods of preparing the coating and the articles are also provided.
