In this study, Damar Batu (DB) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. DB is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (Mw), polydispersity index (Mw/Mn) and glass transition temperature (Tg). Neat plasticized films of DB are investigated for mechanical, water vapor transmission...

Background & Aims: Biocompatible packaging based on edible films containing active agents used in food to improve quality, extending product shelf life and reducing the risk of pathogen growth . The objective of this study was to prepare composite films from chitosan and starch containing 0, 0.5, 1 and 2% pomegranate pell extract (PPE) and to evaluate their antimicrobial, antioxidant and optica...

Hydrosol is a side product of essential oil extraction from plants. In this study, the effect of various ratios (5-100 %v/v) of cinnamon hydrosol replacement in the formulation of edible gelatin films was investigated. Physical properties were evaluated and the antibacterial properties of gelatin films against Staphylococcus aureus, Staphylococcus saprophyticus and Staphyl...

Titanium nitride-Copper (TiN-Cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. The influence of Cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. Structural properties of the films were studied by X-ray diffraction pattern. Topography of t...
