En este trabajo se reporta la síntesis y caracterización de un copolímero basado en poli(anilina) (poli(ani)) y poli(ácido metacrílico) (poli(maa)), con el objetivo de desarrollar un sistema polimérico inteligente con perspectivas de aplicación en la remediación del agua. El sistema poli(maa-co-ani) se obtuvo mediante polimerización química in situ y se caracterizó mediante espectroscopía infrarroja por transformada de Fourier (ftir), espectroscopía ultravioleta-visible (uv-Vis), difracción de rayos x (drx) y análisis termogravimétrico (tga). Los resultados de ftir evidenciaron la presencia de grupos funcionales característicos de ambos componentes, así como posibles interacciones intermoleculares entre grupos amino y carboxílicos. Los espectros uv-Vis mostraron variaciones en las bandas de absorción en función del pH, asociadas a cambios en el estado electrónico del sistema. Asimismo, el análisis de drx indicó modificaciones en el orden estructural respecto de la poli(ani) prístina, mientras que los resultados de tga revelaron variaciones en la estabilidad térmica atribuibles a la copolimerización. En conjunto, estos resultados confirman la obtención de un sistema polimérico con propiedades fisicoquímicas modulables y comportamiento pH-responsivo, lo que permite establecer una base para futuras investigaciones orientadas a evaluar su potencial en aplicaciones de remediación del agua.
