摘要：

Nano-CdS particles, as formed in reverse micelles, have been immobilized into polyurethane (PU), via surface-modification with 4-hydroxythiophenol or 2-mercapto-ethanol, followed by polyaddition of ethylene glycol with toluenediyl 2,4-diisocyanate: the resulting composite, CdS-PU, obtained as powder, can be dissolved in organic solvents such as DMF and formed to make nano-CdS-containing transparent PU films, which show a quantum-size effect and are utilized for photocatalytic H-2 generation.
