Abstract

Cinnamon bark extract (CBE) derived silver nanoparticles (AgNs) and PVA have been used to prepare CBE-PVA-AgNs films by solution casting method. X-Ray diffraction (XRD) studies confirmed the enhancement of crystallinity and silver peaks appeared around 38.12° and 44.41°. Small shift of the silver peak (∼ 2°) in the composite film indicated interaction of AgNs and the PVA. Scanning electron microscope study specified silver grain size varying from 30- 50 nm.The FTIR study approves the complex interaction of the AgNs with the PVA. The UV–visible spectrum showed the presence of silver peak around 430 nm. Enhanced protein adsorption indicated increased biocompatibility of the films which is important for their biomedical applications. Frequency (0.0–10.0 kHz) dependent film conductivity (σ) and dielectric permittivity (ε) also increased largely showing low dielectric loss factor (tan δ < 1.0). The films exhibiting multifunctional properties are suitable for their applications in electronic devices, optoelectronics and packaging industries.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
