The surface tension between the hydrophobic core and the solvent is known to play a major role in the self-assembly of diblock copolymer micelles in solution. Coulombic forces are also very important in the case of aggregates with weakly charged coro

We present a comprehensive study of the interaction of spherical polyelectrolyte brushes (SPBs) with cationically modified polyacrylamide (CPAM), calcium carbonate (CaCO3) particles, and cellulose fibers. A link to the use of this system as a model f

Analytical expressions for transverse electron spin relaxation induced by small angle motion were derived for the first time within an anisotropic model for rotational diffusion by using an approximation of the spin Hamiltonian and its variation duri

Confinement effects in ionomeric poly(isoprene) homopolymers and poly(styrene)–poly(isoprene) diblock copolymers have been studied by pulsed high-field electron spin resonance spectroscopy. The reorientation of paramagnetic tracers (spin probes) be

The size of ion clusters, distances between them, and the dynamics of their environment in ionically functionalized diblock copolymers were characterized by variable temperature continuous-wave electron paramagnetic resonance (CW EPR) and pulse doubl

Double electron-electron resonance (DEER) spectroscopy is introduced as a new tool for the characterization of mesoscopic structures in polymers. This method can characterize distance distributions between spin probes in a range between 1.5 and 8 nm

The self-assembly of ionically end-capped, symmetric polystyrene-polyisoprene diblock copolymers (PS-b-PI) has been studied. Structural data obtained from small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) were correlated

Organically modified aluminosilicate mesostructures were synthesized from two metal alkoxides with the use of poly(isoprene- b -ethyleneoxide) block copolymers (PI-b-PEO) as the structure-directing molecules. By increasing the fraction of the inorgan
