Abstract

This article focuses on the synthesis and characterization of starch-based nanocomposite films reinforced with carbonate intercalated magnesium-aluminum layered double hydroxide (LDH) as an inorganic filler. The study evaluates the optical, electrical, dielectric, and mechanical properties of these films with varying LDH content (0–7 wt %). Results show that increasing LDH content enhances optical absorption, reduces the optical band gap, increases refractive index and optical conductivity, and improves mechanical strength up to 5 wt % LDH, beyond which some properties decline. Electrical characterization reveals decreased conductivity and dielectric loss tangent with higher LDH content, indicating improved dielectric behavior suitable for optoelectronic applications, with 5 wt % LDH identified as the optimal filler concentration for balanced performance.
