4. 2. Dynamic interactions of interfacial polymers

   Author : Mark Plunkett; KTH; []
   Keywords : surface chemistry dynamic polymer interactions QCM AFM MASIF surface forces adhesion friction;

   Abstract : The relationship between the amount and conformation of apolymer at the solid-liquid interface, and the resultinginteraction forces between two such surfaces has beeninvestigated. With a degree of control of the polymerconformation, by varying the temperature, solvent quality,polymer charge density etc, it has been possible to measure andinterpret the resulting changes in the surface interactions.

5. 3. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers

   Author : Marcus Schmidt; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; free-volume theories; refractive index; Lorentz-Lorenz equation; loss tangent; Avrami equation; freezing fractions; copolymers; polymer blends; pressure dilatometry; Tait equation of state; free-volume distributions; pressure-densified polymers; entropy of melting; dynamic-mechanical analysis; positronium; positron annihilation; free volume; cavity size; polymers; bulk modulus; PVT; phase separation; compressibility; thermal expansivity;

   Abstract : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. READ MORE

6. 4. Signal Enhancement by Dynamic Polymers in Quartz Crystal Microbalance Applications

   Author : Gunnar Dunér; Olof Ramström; Ian Nicholls; Andra Dedinaite; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Signal enhancement; QCM; polyelectrolytes; hydrogel; iniferter; photopolymerization; dynamic polymers; Chemistry; Kemi;

   Abstract :  This licentiate thesis presents studies of signal enhancement by dynamic polymers in quartz crystal microbalance (QCM) applications. The aim of the study has been to determine the potential for the use of polymers on QCM sensors for signal enhancement in molecular interaction studies. READ MORE

7. 5. Dendrimers and dendronized polymers : synthesis and characterization

   Author : Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

   Abstract : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. READ MORE
