Kinetics of phase separation and thin film formation of multiresponsive polymers In this thesis we were interested in studying the deposition of layers formed by stimuli responsive colloidal soft particles using a surface acoustic wave method: “Quartz Crystal Microbalance with Dissipation Monitoring (QCM D)”. This thesis is divided into four chapters: chapter 1 gives an introduction to the structural properties of polymers and glasses in solution and at interfaces chapter 2 presents the principles of the QCM D monitoring technique in terms of the physical meaning of its main output (the normalized resonance frequency shift Δfn n and dissipation factor shift ΔDn) and important parameters to consider while carrying out our study (temperature and light control). Chapter 3 is dedicated to deposition control of soft layers formed out of dual stimuli responsive colloidal particles of Poly (triethylene glycol acrylate co Spiropyran acrylate) (P(TEGA co SPA)). In this chapter we examine the concomitant effect of light and temperature in order to manipulate the formation process of soft glassy films and their subsequent structural response. Chapter 4 presents the kinetics of the deposition of Poly(N isopropylacrylamide) P(NIPAAm) soft glassy layers. In this chapter we focus on the effect of temperature and concentration on the isothermal glass formation below and above the phase separation temperature using a twostep kinetic model. We also provide a subsequent analysis of the viscoelastic properties of the deposited layers in non isothermal mode and compare it with their properties in isothermal mode. The present study extends the state of the art in two main disciplines. The first discipline is fundamental research in glass sciences and the second discipline is the research of multi stimuli responsive polymers where our findings would be of great interest for applications that need remote controlled switching especially in microfluidic chips and biomedical applications.
