MOLECULAR STRUCTURE AND FORMATION OF CHITOSAN AND PECTIN BASED THIN FILMS
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2016, Vol 0, Issue
Abstract
In this study using methods of Atomic force microscopy (AFM) and Quartz crystal microbalance with dissipation monitoring (QCM-D) the special characteristics of formation and architecture of thin films coatings based on natural polysaccharides chitosan and pectin were investigated. A layer-by-layer (LbL) deposition technique for assembling of oppositely charged layers was used. The main factors, which have an influence on the process of thin film formation and molecular structure of these coatings, were investigated.
