Research in this department centers on elucidating the connection between the microscopic structure and the macroscopic properties of rubber mixes and crosslinked reinforced rubber systems. Special emphasis focuses on advanced fundamental research of the physical properties of elastomers and the implementation of results in micro-structure based models. The main research topics of this department are:

Contact mechanics and friction Theory of rubber friction Friction and traction of tires Contact mechanics at rough (fractal) interfaces Hysteresis and adhesion friction
		Aging and Wear Physical aging Aging phenomena of the filler network Crack propagation and fatigue Friction and wear mechanisms
Filler networking and reinforcement Theory of filler induced reinforcement Material models for FE-simulations Characterization of fillers and filler networking Molecular dynamics simulations Nano-composites (Clay, CNT, PAOS, in-sito silica)
		Dielectric and mechanic relaxation spectroscopy High-frequency properties Polymer-filler and filler-filler interactions Interphase dynamics of filled elastomers Structure and properties of the filler network Charge transport mechanisms Microwave heating
Polymer networks and blends Theory of rubber elasticity Evaluation of network parameters Characterization of blend morphology Filler distribution in blends
		Rheology Molecular rheology of entangled polymer melts High pressure capillary viscosimetry Wall slip phenomena Elastic turbulent flow Dielectric analysis under shear flow Rotational rheometry Magnetorheology
