INMA Junior: Ruggero Rossi

Seminario INMA Junior: “Shine light on surfaces: Advancements in smart materials through photoresponsive polymers”

El próximo miércoles 10 de noviembre a las 12:00 tendrá lugar el próximo Seminario Junior del INMA en la Sala de Grados del Edificio A de la Facultad de Ciencias en el Campus San Francisco. Tras el seminario tendrá lugar un picoteo al que todos los asistentes podrán acudir.

El seminario titulado: “Shine light on surfaces: Advancements in smart materials through photoresponsive polymers” será ofrecido por Ruggero Rossi  del CLIP Group, del Instituto de Nanociencia y Materiales de Aragón, INMA, instituto mixto del CSIC y la Universidad de Zaragoza.

Resumen: Azobenzenes and azobenzene-like photo-switches are best suited molecules for obtaining of smart photo-responsive materials, revealing their potential to modulate surface properties such as adhesivity and wettability when exposed to light. The study of this kind of photo-switches allows designing a material based on the dynamic properties of the molecules and explores dynamic interplays for applications in different fields. Their potential stems from the reversible trans–cis photoisomerization and relative ease of synthetic modification, allowing for tuning the lifetime of the metastable cis-state from sub-milliseconds up to several years. Employing 3D printed liquid crystalline elastomers enhances this versatility, leading to the development of artificial muscles with superior flexibility and responsiveness. By incorporating azobenzene, these muscles can be actuated using light irradiation. This research underscores the multifaceted capabilities of photoresponsive polymers, offering promising strides in materials science, energy storage, and biomimetic robotics.
