Resumen
[ES] Este trabajo tiene como objetivo la síntesis de un material bidimensional basado en el desarrollo de nanofibras de polianilina (PANI), la cual interconecta una matriz de puntos cuánticos de carbono y su estudio espectroscópico y morfológico. Para ello, se han utilizado puntos cuánticos de carbono (CDots), que son nanopartículas de dimensión cero que muestran fotoluminiscencia, permitiéndonos una gran
variedad de aplicaciones, destacando su utilización en células solares como antenas fotónicas. La
metodología utilizada para sintetizar este nanomaterial ha sido la síntesis in situ del PANI en presencia
de los CDots previamente sintetizados por síntesis hidrotermal y microondas. Una vez realizada la
síntesis, se ha depositado sobre un vidrio mediante spin coating. El objetivo es el estudio de las
propiedades optoelectrónicas. Por lo tanto, los nanocompuestos sintetizados se han caracterizado
espectroscópicamente mediante el uso de la espectroscopía de absorción ultravioleta-visible (UV-Vis) y la espectroscopia de fluorescencia infrarroja (FTIR), confirmando esta última la interconexión del PANI con los CDots, formando un entramado tridimensional.
[EN] This work aims at the synthesis of a two-dimensional material based on the development of polyaniline (PANI) nanofibers, which interconnect a matrix of carbon quantum dots and their spectroscopic and morphological study. For this purpose, carbon quantum dots (CDots) have been used, which are zerodimensional nanoparticles showing photoluminescence, allowing us a wide variety of applications, highlighting their use in solar cells as photonic antennas. The methodology used to synthesize this nanomaterial has been the in-situ synthesis of PANI in the presence of CDots previously synthesized by hydrothermal and microwave synthesis. Once the synthesis was completed, it was deposited onto glass via spin coating. The objective is the study of optoelectronic properties. Therefore, the synthesized nanocomposites have been spectroscopically characterized using ultraviolet-visible (UV-Vis) absorption spectroscopy and infrared fluorescence spectroscopy (FTIR), with the latter confirming the interconnection of PANI with CDots, forming a three-dimensional network.
