摘要： A composition and a method for manufacturing the composition are provided that includes a thermoplastic polyurethane (TPU) and a second component in an amount in the range of about 3% to about 60% by weight of the composition. The second component includes at least one reactive diluent, monomer, or oligomer (RDMO). The RDMO and/or the TPU may be cross-linked to form a semi-interpenetrating polymer network or an interpenetrating polymer network. The RDMO provides improved physical properties, such as rigidity, durability and strength, to the TPU. The polymer network may be bonded to other layers for certain applications, such as windows and flooring, to improve flexibility and strength, inhibit shattering and/or resist scratching and staining.

摘要： 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 m2/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.
