Se obtuvieron fibras puras de poliacrilonitrilo (PAN) con un diámetro a escala micrométrica y se recogieron radialmente utilizando un sistema de hilatura húmeda por inmersión. Esta técnica es un método rápido y sencillo para fabricar fibras de PAN micrométricas. El diámetro de la fibra puede controlarse fácilmente ajustando el tamaño de la hilera. Las microfibras de PAN uniformes, lisas y continuas se modificaron adecuadamente mediante estabilización térmica y saponificación alcalina para obtener fibras sensibles al pH. Se investigó el efecto del tamaño del diámetro de la fibra en el comportamiento de actuación química en términos de características de cambio de longitud bajo la influencia de la solución de pH. Las microfibras mostraron un comportamiento de expansión/contracción y generación de fuerza estimulado por cambios en el pH ambiental. Las propiedades estructurales y químicas de las fibras se caracterizaron mediante técnicas de espectroscopia FT-IR y microscopía SEM.
