“…Corn starch nanoparticles (CSNPs) are an odorless and tasteless white powder. It's used in wide applications of nanotechnology such as food and nanomaterials production, increasing bioavailability, protecting against chemical and biological deterioration, and boosting the physical properties [26]. Biopolymers are natural polymers that can be obtained from various kinds of sources.…”

“…The features of thermoplastic CSNPs are specifically covered after examining the botanical sources of starch and the methods used for extracting them, along with popular processing methods like solvent casting, extrusion, and film blowing. Additionally, it has been stated that additives like essential oils and functional organic compounds like carvacrol, eugenol, and cinnamic acid concentrate on the antioxidant and/or antibacterial characteristics of CSNPs and improve the CSNPs use in smart packaging [26]. The primary goal of this research is to determine the effect of CSNPs on the morphological, optical, and dielectric properties of the PVA/PMMA/PAAm blend in order to make sure that it will be suitable for various optoelectronic devices and biological applications.…”

The present study was conducted to explore the impact of corn starch nanoparticles (CSNPs) on the morphological, optical, and dielectric behaviors of the PVA/PMMA/PAAm (PPP) hybrid polymer matrix. The resultant PPP-CS nanocomposite films were synthesized employing the solvent casting procedure. Scanning electron microscope(SEM) images of the as-synthesized films revealed the successful embedding, homogeneity, and fine dispersion of CSNPs within the host PPP. No changes in the infrared ray(IR) band positions were seen upon embedding. The absorbance-λ chart illustrated an absorption band at 220 nm with red-shift toward higher wavelengths, which points out the semi crystalline structure of PPP-CS films. The optical coefficients were improved upon inclusion of CSNPs. The optical bandgap energy reduces from 4.50 to 4.12 eV as CSNPs' weight percentage increases from 0 wt% to 4 wt%. Furthermore, the refractive index values for PPP-CS films are in the range of 0.5 and 2.5. The dielectric constants of the obtained films decreased with the increase in CSNPs, except for the conductivity. The embedding of a small amount of CSNPs into the hydrophilic matrix significantly improved the composite's bioactivity. The inhibition zone diameters of Staphylococcus aureus bacteria were calculated to be 0, 26, and 32 mm for 0 wt%, 2 wt%, and 4 wt% CSNPs, respectively. The findings of this study are significant for the development of novel nanocomposite materials with antibacterial activity for optoelectronic device applications.
