| Introduction: |
LPRT carries out both basic and applied research, which covers a wide range of topics including theoretical studies, the characterization of raw materials, the development of new compounds and materials, the solution of technological problems, the improvement of product quality, the increase of productivity, and the solution of customer complaints. The study of interfacial interactions and structure-property correlations in heterogeneous polymers systems is in the focus of attention of the laboratory for many years. Methods were developed at the laboratory for the surface characterization of micro- and nanofillers and for the prediction of the strength of interaction. Specific methods were developed and/or implemented for the study of micromechanical deformation processes governed by interactions. Unique models were created for the description of interfaces and interphases including one that describes the formation of graded interfaces in composites and their effect on composite properties. The laboratory has extensive experience in the quantitative characterization of filler aggregation and in the prediction of its effect on properties. The laboratory also studies the degradation and stabilization of polymers and the melting, crystallization and morphology of crystalline polymers. In recent years, considerable research has been done on bio-related (starch, wood, lignin, cellulose acetate, PLA) and functional (oxygen and water free packaging, controlled release of additives) materials. The Textile Chemistry Group of the lab focuses mainly on the surface modification of cellulosic fibers by nonthermal plasmas and on the development of environmentally friendly textile technologies by the use of enzymes. Low frequency ultrasound is applied for the intensification of enzymatic textile processes and the group studies the effect of sonication on enzyme-substrate interaction. |
