Nanoparticulas de magnetita para recubrimientos marinos

Abstract

El propósito de este trabajo es la síntesis y caracterización de nanopartículas de magnetita para su utilización como aditivos en recubrimientos marinos. Los cuales pueden ser de gran utilidad para prevenir, proteger y retrasar el proceso corrosivo en estructuras marinas. En el proceso de síntesis se ha utilizado una temperatura, tiempo de reacción y agitación determinadas, lo cual nos ha permitido obtener nanopartículas de un tamaño concreto. La caracterización de estas partículas se ha llevado a cabo mediante difracción de rayos X, microscopia electrónica de barrido (SEM), microscopia electrónica de transmisión (TEM), infrarrojo con transformada de Fourier (FTIR) y ensayos de magnetismo (VSM). Las nanopartículas sintetizadas tienen un tamaño de alrededor de 7 nm, aunque su determinación ha sido muy complicada al tender a aglomerarse. Para evitar en la medida de lo posible el proceso de aglomeración se han añadido diferentes cantidades de H3PO4.

The purpose of this work is the synthesis and the characterization of magnetite nanoparticles to be used as additives in marine coatings. Which can be very useful to prevent, protect and to delay the corrosive process in marine structures. In the synthesis process a certain temperature, a reaction time and agitation have been used, which has allowed us to obtain nanoparticles of specific size. The characterization of these of particles has been carried out by X-ray Powder Diffraction, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FTIR) and magnetism essays. The synthesized nanoparticles have a size of around 7 nm, although their determination has been very complicated as they tend to agglomerate. To avoid as far as posible the agglomeration process it has been added different amount of H3PO4.

Lan honen helburua magnetita nanopartikulen sintesian eta karakterizazioan datza, itsas estalduretan gehigarritzat erabiltzeko. Hauen bidez itsas egituren prozesu korrosiboa sahiestu, babestu eta atzeratu daiteke. Sintesi prozesuan temperatura, erreakzio denbora eta agitazio zehatzak erabili dira, eta hauen bidez tamaina konkretuko nanopartikulak lortu ahal izan dira. Partikula hauen karakterizazioa X ispien difrakzio, ekorketa mikroskopia elektronikoa (SEM), transmisio mikroskopia elektroniko (TEM), Fourierren bidez eraldatutako infragorri (FTIR) eta magnetismo saiakuntzen (VSM) bidez egin da. Naiz eta sintetizatutako nanopartikulen neurria zehaztea zaila den, biltzeko joera dutelako, 7 nm inguruko neurria daukate. Nanopartikulen biltzeko joerari aurre egiteko H3PO4 kantitate desberdinak gehitu zaizkio.
