Exposure Technique

Various techniques have been used to prepare polymer nanocomposite thin films that involve tedious work and consume considerable amount of materials and time. In this study, nanocomposite thin films of poly (3-hexylthiophene -2, 5-diyl) (P3HT), stearic acid and CdSe nanoparticles were fabricated by a stamping method which is a modification of Langmuir Schaefer technique. The CdSe nanoparticles were then grown in-situ between subsequent layers of thin film by gas exposure technique. Their surface-pressure (-A) isotherms and morphology were investigated. The surface-pressure isotherms revealed that, impurities in water subphase affect the profile of Langmuir monolayer. Stearic acid was found to be more dominant as compared to P3HT. The modified Langmuir Schaefer technique produced fairly smooth, large area nanocomposite thin films as shown by the AFM images. A prominent advantage of this procedure is that it requires only small amount of materials.

ABSTRACTMagnetic cobalt ferrite nanoparticles provide a pathway towards nanocomposites, due to the ability to fabricate particle-matrix thin films in the submicron range. In this work flexible particulate 0-3 type thin-films, composed of magnetic CoFe2O4 particles (8-18 nm) and ferroelectric poly(vinylidene fluoride-co-hexafluoropropene) (P(VDF-HFP)) polymer, have been fabricated via multiple spin-coating. The thickness of the thin-films was controlled in the range of 500 nm to 1.2 μm, with magnetic particles dispersively embedded in the polymer matrix. Structural information was analyzed by TEM, XRD, HRTEM and SEM. The dielectric and magnetic properties of the cobalt ferrite/copolymer thin films are systematically investigated. The nanocomposite thin films exhibit composition-dependent effective permittivity and loss tangent, as well as temperature and composition-dependent specific saturation magnetization (Ms). The coercivity (Hc) was not affected by the composite’s composition. These films have great potential in smart magnetic devices and biomagnetic applications.
