Radiation curable primer adhesive
The present invention involves a 100% solids, radiation curable adhesive formulation for adhesion to EVA. This formulation may have varying compositions, as discussed in detail herein. However primarily the composition may comprise at least a monomer, and a chlorinated additive. Photo initiators may be used to allow for low temperature UV or other radiation curing. Other additives may be used to enhance functional features in various ways. In use, the present invention may be coated on a surface of EVA and then cured, and may be adhered to a substrate using only a layer of adhesive on the substrate, in contrast to the structures of the prior art, which require at least two sided adhesive application, among other complexities.

Water purification material for petrochemicals
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 Å. 3D porous networks of NL-assisted PS branched CNF supported PU can provide a hydrophobic, oleophilic surface with a water contact angle of approx 148±3°, rapidly gravity separating hexane and water without external force.
