Description of the LCPP
The Laboratory for Characterisation and Processing of Polymers (LCPP) is active within the Institute for Engineering Materials and Design at the Faculty of Mechanical Engineering, University of Maribor, Slovenia. Six well equipped laboratories enable research activities in a wide variety of newly developing sciences and technologies. The Institute`s interdisciplinary research teams are involved or coordinate numerous international and national projects and industrial research activities. 9 full professors, 7 associate professors, 3 assistant professors, 15 assistants with PhD, 2 assistants with master degree, 17 researchers, and 7 technicians are active at the institute at the moment. Numbers of doctoral students are enrolled in the research activities as well.
The team of the Laboratory for Characterisation and Processing of Polymers performs extended polymer analyses, with emphasis on fiber forming polymers. Special attention is given to the study of structural parameters, surface characterization (surface morphology, chemistry and interaction ability), modification and functionalization of polymers and polymeric materials (fibers/foils/films) as well as the development of new and ecologically friendly processes. A wide range of possibilities for sample preparation, depending on the desired application and the polymer starting material are used. For thin films, spin coating is the method of choice while for the coating of fibers dip, spray or roller coating apparatuses are used. Electro spinning and 3D printing are the methods used in the lab for preparation of PS nano structures as well as for example PS/sol gel hybrid nano fibers. Ink jet printing is used for functionalization of flat surfaces (e.g. development of microfluidic devices and sensors). In addition LCPP offers several methods which are able to alter the prepared materials such as ozonization, plasma treatment or ultrasonication to mention only a few. The evaluation of modification methods and the preparation of materials is performed by surface property analysis (surface morphology and structure, surface chemistry, surface charge, the quality and quantity of specific dissociable and accessible polymer surface groups, their dissociation constants, wettability etc.) in combination with other analytical concepts. Accordingly, development of bioactive polymeric materials used in the medical sector (3D structured soft materials for tissue engineering and wound dressings), functionalized biodegradable polymeric materials used in packaging, paper, textile industry and others are our research target.
