Modificação de membrana de poliamida via sol-gel e incorporação de composto de európio (III) luminescente

Abstract: . Over the last decades, the combination of different technologies to search for systems with new properties and features has brought various segments of biological and earth sciences together. Additive manufacturing, known as rapid prototyping, combined with the sol-gel methodology enables the production of novel systems with applications in many scientific fields. In this work, flexible polyamide membranes were obtained by additive manufacturing, functionalized by the sol-gel methodology, and incorporated wi… Show more

“…Compared to other polyamides, PA12 absorbs less water due to its relatively long hydrocarbon chain, and it displays flexibility, controlled porosity, high resistance to impact even at low temperatures, excellent stress crack resistance, high processability, good fatigue resistance under high-frequency cyclic loading, and excellent resistance to commonly employed organic solvents [2]. Therefore, PA12 membranes are good candidates for use as wound dressings and drug carriers, as already observed in other works by our group [3][4][5][6].…”

“…PA12 membranes (measuring 5.0 × 7.0 cm and with thickness of 200 μm) were prepared as described previously [5]. Then, the PA12 membranes were cut into circular shape with diameter of 1 cm, placed in a 50 mL beaker containing distilled water, and subjected to constant magnetic stirring for 2 h. Next, the PA12 membranes were dried at room temperature, and excess PA powder, originating from the raw material during SLS, was removed.…”

“…Através da MA, é possível a obtenção de membranas constituídas de poliamida. A técnica baseia-se na construção por camadas de peças tridimensionais complexas utilizando processos automatizados, a partir de um modelo digital gerado em programas computacionais (CAD -Computer Aided Design) .
