A permanent increase in the demand for polymers is closely related to the issue of their degradation. Typically, aromatic amines or phenol derivatives are used to protect materials against ageing. In our studies, we propose to use natural pro-ecological substances, such as polyphenols extracted from green tea leaves, to protect elastomers against ageing. Several extracts from Sencha and Gun Powder...
This article presents the electrochemical analysis of the oxidation of rutin and green tea extract solutions and the antioxidative properties of these substances. Flavonoids and other polyphenols contained in green tea have antioxidative properties due to the presence of various numbers of hydroxyl groups in different arrangements. The investigation of the oxidation of green tea extracts was performed...
