The present invention provides a method comprising rotational molding a powdered polyolefin elastomer composition to form a skin, the composition formed by spray drying an aqueous polyolefin dispersion composition which is itself formed by melt blending a polyolefin composition comprising an olefin block copolymer, a dispersing agent, and water, wherein said aqueous dispersion preferably has a pH less than 12.

Functionalizable nanopatterned monolayers comprise one or more block copolymers, each containing one or more hydrophobic blocks and one or more hydrophilic blocks. The one or more hydrophilic blocks of at least one of the block copolymers can be terminated by a modifiable functional group, to which a functional moiety, such as a biological molecule, can be attached. The surface concentration of the modifiable functional groups on the monolayer can be controlled by adjusting the properties of the block copolymers, such as their size, their chemical makeup, and the relative proportion of the block copolymer containing the modifiable functional group, and the conditions, such as surface pressure, under which the monolayer is formed and/or transferred to a substrate. The nanopatterned monolayer can be transferred to a substrate to form a functionalizable nanopatterned nanocoating, which is useful in applications such as biosensors.
