Abstract:

Antifouling coatings have to provide antibacterial performance combined with good mechanical and chemical properties. The good anticorrosive performance of tannins on steel surfaces and antibacterial activity of phytochemicals from conifers could provide a solution in the form of Scots pine bark extract. In this study, epoxy compositions with different ratios of the characterised extract (TPC, HPLC analysis of phytochemicals) were tested physically (density), mechanically (Shore D hardness, three-point bending test, Charpy impact test), chemically (DSC curing analysis, FTIR spectroscopy, chemical resistance), and microbiologically (antibacterial activity). The results were analysed and the performance of the composites was evaluated.

Ion Exchange

Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or basic...

Ion-Exchange Chromatography

Ion-exchange chromatography, or IEC, is a technique for separating ions based on their affinity for the stationary phase. The stationary phase is a cross-linked polymer resin with covalently attached ionic functional groups. The functional groups can be either positively charged (cation exchangers) or negatively charged (anion exchangers). A cation exchanger consists of a polymeric anion and active cations, while an anion exchanger is a polymeric cation with active anions. The choice of...
