This work focuses on an optical and morphological comparative study of hybrid functional polymer porous films on glass substrates using the spin coating technique. The covering of these membranes, by a predeposited Zn²⁺ seed layer, was done applying the dip casting technique, which allows the synthesis of a large area and the control of the orientation of ZnO nanoparticles. It was possible to observe changes on the optical properties and surface morphology, which were attributed to both the spatial structure of the macromolecule and their interaction with the inorganic nanoparticles. It was also clear that hybrid porous matrices exhibit a blueshift with decreasing particle size.

In the present work, we report a simple experimental strategy for the one‐step electrochemical synthesis of nanogranular Cu ₂ O films by copper anodization in fluoride‐containing ethylene glycol media. Microscopic exploration using field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM) and transmission electron microscopy (TEM), shows the formation of spherical shape grains with sizes ranging from 20 to 40 nm. Raman and X‐Ray Photoemission Spectroscopy (XPS) results indicate that only Cu ^I oxide is obtained. A band gap energy E _g =2.01 eV is estimated from UV–vis reflectance spectroscopy indicating that an indirect transition mechanism between semiconductor bands takes place. These evidences indicate that the present synthesis of nanogranular Cu ₂ O films is a promising method for obtaining improved properties of materials for the design of photoelectronic devices.

In this study, we examined the synthesis, and characterization of TiO₂/poly(N-maleoylglycine-co-acrylic acid) (TiO₂/poly(MG-co-AA)) nanocomposite. The nanocomposite was prepared by the dispersion of TiO₂ nanotubes in a water solution of the polymer (3% w/w) and then it was lyophilized. The nanocomposite was characterized by FTIR and Raman spectroscopies. The incorporation of TiO₂ nanotubes to the polymeric matrix was determined by transmission electron microscopy (TEM) from which TiO₂ nanotubes in the inner of copolymer with diameters ranging between 90 and 100 nm were observed. The overall morphology of the previously synthetized nanotubes was determined by scanning electron microscopy (SEM). For the nanocomposite system, the morphology was studied by atomic force microscopy (AFM) from which a grain shape structure was observed. This process resulted in a new nanocompsite material with an average grain diameter estimated by SEM and AFM ranging between 210-240 nm. It was observed that the nanotubes were homogeneously dispersed within the polymeric matrix. The prepared material could be suitable in the design of electronic devices and additionally could have potential applications as biomaterial.
