Wetting, spreading and evaporation of nanoparticle suspensions and polymer solutions on substrates
Characterize the spreading and evaporation processes of complex fluids on solid substrates; study the morphology of the nanoparticle layer after complete evaporation; formulate a theory describing spreading and evaporation process on hard, deformable and porous substrates.
Originality and innovative aspects: Despite the important technological applications, the state-of-the-art theory is not able to predict all stages of the evaporation process2. No satisfactory theory exists for particle suspensions, patterned surfaces and soft substrates. This WP in which investigation of the evaporation process in its whole complexity is planned, will bring about a breakthrough into the field.
Methodologies: Experimental methods include light scattering, refractive index measurement, macro- and microrheology measurements, measurement of complex elastic modulus of the solid substrates, measurement of equilibrium and dynamic surface tension as well as of dilatational surface rheology, ellipsometry, dissipative quartz-crystal microbalance, optical methods, microscopy. A theoretical method will be developed in cooperation with LU. Collaborations are also planned with TUD and MPIP which have complementary expertise. ESR will perform experimental studies, whereas ER will be responsible for the theoretical and computational studies.
