Vapor phase polymerization can be used to synthesize a 3D porous network of polystyrene-containing, branched carbon nanofibers on polyurethane(s), optionally using natural light (NL) initiation. NL styrene polymerization in a confined reactor containing CNF-grafted PU can provide a stable porous network. The NL can vaporize the styrene by increasing the reactor temperature and generate styrene radicals. Without CNF, the polymerization on polyurethane (PU) provides a delicate, fragile surface. Radical styrene in vapor phase can interact with CNF to produce polystyrene branches by generating active sites on CNF, while reinforcing the 3D porous structure. After polymerization, the PU surface area increased from 9 to 184 m.sup.2/g and pore size decreased from 2567 to 10 . 3D porous networks of NL-assisted PS branched CNF supported PU can provide a hydrophobic, oleophilic surface with a water contact angle of approx 1483, rapidly gravity separating hexane and water without external force.

Described herein are compositions suitable for use as binder components for inclusion in printing inks and coatings, such as those used in the gravure and flexographic printing process and which are printed on substrates such as polyolefin (e.g., polyethylene, polypropylene) and poly(ethylene terephthalate) (PET). The compositions are non-aqueous dispersions in which an one or more ethylenically unsaturated acrylates or (meth)acrylates is polymerized with a polyurethane, polyurethane-urea or polyurea in a non-aqueous polymerization medium, such as esters, ketones, and mixtures thereof, forming polymeric hybrid resins in the polymerization medium, which are solvent-dispersible hybrid resins of polyurethane-polyacrylate, polyurethane-urea-polyacrylate, and polyurea-polyacrylate. Films of hybrid resins are also disclosed. These materials exhibit improved film adhesion and are suitable for flexographic and gravure printing inks, especially for printing applications where adhesive lamination bond strengths are required, especially plastic films packaging applications.
