Abstract

Composite films based on furcellaran (FUR) and carbon quantum dots (CQDs) has been obtained by casting method. The effects of CQDs films as nanofiller on optical, physical, mechanical and microstructural properties of furcellaran films were evaluated. The synthesized composites were characterized using Scanning Electron Microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and ultraviolet-visible spectroscopy (UV-Vis). The results from scanning electron microscopy (SEM) confirmed that the composite films have homogeneous and compact structure, with no fractures or cracks. Tensile strength (TS) and elongation at break (EAB) values increased with the increase of CQDs concentration. The UV-Vis results confirmed that composite films exhibited enhancement of photosensitivity. The FUR/CQDs composite films have high potential to be used in many applications.
