ABSTRACT

Objective: Kappa-Carrageenan, a natural polymer is a product derived from seaweeds has been gaining vast attention on researches because of its biodegradability and low cost production. On the side, Nanotechnology, the emerging Science of nanoparticles have been indulging the world with its new approaches on improving the characteristics of the medium used. This study differentiated the physicochemical properties of the films without and with the incorporation of Zinc Oxide Nanoparticles to kappa-Carrageenan. Materials and methods: Incorporation of ZnONps to kC was done. Physicochemical properties, namely: moisture content, degradation time, wavelength spectra, structural composition, and surface morphology was differentiated between biocomposite films with and without the ZnONps.

Results and conclusion: After several tests, Zinc Oxide Nanoparticles incorporated to kappa-Carrageenan exhibited some changes to its physicochemical properties: lower moisture content and longer degradation time was revealed; ZnONps was seen in the surface of the biocomposite film. However, structural composition analysis showed that no new formation of functional group was seen. The biocomposite films could be a substitute with the existing drug capsule because of its longer decomposition, low water content and secured safety of the drug’s quality.

KEYWORDS: Zinc Oxide Nanoparticles (ZnONps), biocomposite films, kappa- carrageenan (kC), physicochemical property
