OBJECTIVE To establish a new method for assembling C60 functional composite by C60 technique using Langmuir-Blodgett (LB) technique.METHOD The LB film was used to prepare a mixed LB film of arachidonic acid (C60 / PVK / CdS) and the interfacial chemical reaction Hydrogen sulfide gas was used to prepare functionalized LB films with C60 / PVK / CdS nanoparticles and characterized by UV spectra.Results C60 PVK / AA with different proportions of C60 could form stable monolayers on cadmium subphase and transfer to LB multilayer films were obtained on solid substrates.The UV spectra of LB mixed films reacted with hydrogen sulfide gas.Conclusion The combination of LB and interfacial chemical reaction can be used to prepare C60 / PVK / CdS nanoparticle Functional composite system
