Abstract
The objective of this study is to pioneer the fabrication of self-supported flexible silica-titania based glass with magnetic properties through low-temperature synthetic routes. In this regard, superparamagnetic iron oxide nanoparticles (SPIONs) were incorporated in the glass matrices (hybrid sol-gel silica precursors). Across the studied compositions, Young's modulus below 370 MPa demonstrate mechanical flexibility comparable to recognized flexible materials such as PET. Notably, the superparamagnetic behav-ior of SPIONs persisted at 300K even after their integration in the self-supported flexible glass matrices.
