The disclosure relates to articles and components thereof, including outsoles, which can be used in conditions normally conducive to the accumulation of soil. In particular, the disclosure relates to articles and components thereof with a material including a hydrogel, where the hydrogel-containing material defines an external surface or side of an article. The hydrogel-containing material can prevent or reduce the accumulation of soil during use. A portion of the hydrogel-containing material is embedded into a substrate body, or a portion of the hydrogel-containing material is disposed on the outer side surface of the substrate body in a junction. The substrate body can have a lip extending from a shaft such that the shaft and the lip form the junction. Embedding the material in the substrate body, or disposing it in the junction, can minimize or prevent delamination of the hydrogel containing material during normal use.

Various laminated compositions comprising sheet metal, methods of manufacture, and use thereof are disclosed.

In present invention, various embodiments provide a photothermotropic composite film. The composite film comprises a matrix and one or more nanostructures comprising a metal oxide semiconductor which is configured to convert radiant energy to thermal energy. The matrix has a property which is changeable based on the thermal energy received by the matrix from the metal oxide semiconductor. In a preferred embodiment, hybridization of the poly(N-isopropylacrylamide) (PNIPAM) hydrogel and antimony-tin oxide (ATO) is provided as the composite film. In this film, the ATO absorbs at near-infrared (NIR) region and acts as nanoheater to induce the optical switching of the hydrogel. The behaviour of this composite film can be used as a new generation of autonomous passive smart windows for climate-adaptable solar modulation.
