“…New materials based on the blends have the potential to develop new material for packaging of medical devices and drugs. Our research and that of several research groups has shown that it is not easy to study the interaction between natural and synthetic polymers [207][208][209][210][211][212][213][214][215][216][217][218]. Very often, the properties of the blends do not meet the scientific and practical expectations.…”

INTRODUCTIONThe biomedical sector requests more and more complex structures in attempts to fulfill the requirements of a multitude of different applications. For this reason, polymer scientists exploit existing compounds and also design new compounds with properties that can be considered as new materials for biomedical applications [1,2]. The applications of polymers are essential in surgery, for prosthetic systems, and in pharmacology, for drug formulation and controlled drug delivery. Polymeric biomaterials are usually used under complex, demanding conditions, and must fulfill stringent requirements relating to their chemical, biological, and physicomechanical properties. Therefore, there is an urgent need for new polymeric biomaterials that can satisfy the demanding performance requirements and standards required for these applications [3]. The development of innovative polymeric biomaterials can be an engine of innovation for new medical treatments and therapies. The existing knowledge clearly shows that the careful optimization of the chemical structure of polymers used in medical implants can result in better clinical outcomes for the implant recipients. Biodegradable polymers play a significant role in the preparation of polymeric materials for biomedical applications. They are preferred candidates for developing therapeutic devices such as temporary prostheses, three-dimensional porous structures as scaffolds for tissue engineering, and as controlled/sustained release drug delivery vehicles [4].At the end of the twentieth century, a new trend in the development of polymeric materials was observed [5]. Many scientific laboratories started to work with polymer blends as potential new materials for medicine (biomaterials), the food industry (biodegradable and photodegradable food packaging materials), and for the electronic industry (conducting polymers). Especially, new materials for biomedical applications based on the blends of two polymers were studied. Cell-based transplantation, CONTENTS

“…The drop was put on the film surface using a syringe and the contact angle was measured by the goniometer (DSA 10 Control Unit, Krüss, Germany). The surface free energy was calculated using the Owens‐Wendt method, as this method is commonly used for the calculation of polar and dispersive components of surface free energy for polymers …”

In this work, thin films made from the blends of collagen and chitosan with silver nanoparticles were prepared and their properties, which are important for potential biomedical applications, were studied. Thin biopolimeric film was obtained by solvent evaporation from collagen/chitosan mixture containing silver nanoparticles. Mechanical properties of the composites were tested in dry condition using a mechanical testing machine. Microstructure of films was analyzed by Atomic Force Microscope. The surface properties were analyzed by contact angle measurements using hydrophilic and hydrophobic liquids. In addition, antimicrobial properties of collagen/chitosan/silver composites were tested during the microbiological test. It was found that the addition of silver nanoparticles to collagen/chitosan film affects several of its properties. Microbiological studies showed that obtained collagen/chitosan/silver nanoparticles materials possess bacteriostatic activity against Staphylococcus aureus.

Abstract:In this study thin films based on a blend of collagen, chitosan and hyaluronic acids were prepared and their surface and mechanical properties were studied. The structure of the films was studied using FTIR spectroscopy, contact angle measurement and AFM images. Swelling and mechanical analyses were also performed. The hair protection possibility of collagen/chitosan/hyaluronic was studied using SEM microscopy and the mechanical testing of hair coated by the blends. It was found that the addition of hyaluronic acid to a collagen/chitosan blend improves the mechanical resistance of biopolymeric films. Samples with the addition of hyaluronic acid were more stable in aqueous conditions and provided higher roughness of surface.
