The segmental dynamics and orientational ordering for the free chain ends of a strongly segregated diblock copolymer, poly(styrene)-b-poly(dimethylsiloxane) (PS-b-PDMS), self-assembled into a lamellar structure, was investigated with 2H solid-state N

As an experimental project proposed to students in fourth year of university, a viscometer was developed, consisting of a small magnet levitating in a viscous fluid. The viscous force acting on the magnet is directly measured: viscosities in the rang

The segmental dynamics of amorphous poly(dimethylsiloxane) (PDMS) in a lamellar poly(styrene)−poly(dimethylsiloxane) diblock (PS−PDMS) is investigated by means of broadband dielectric spectroscopy. Because of the absence of normal mode in PDMS, w

Polybutadiene network was swollen with short perdeuterated network-like chains (PBD). Deuterium NMR spectra of these probe chains are measured as the rubber matrix is uniaxially elongated. Due to the presence of two kinds of deuterons (methylene and

The segmental ordering within the sublayers of a lamellar polystyrene-poly dimethylsiloxane-polystyrene triblock (PS-PDMS-PS) is examined by NMR. The carbon and deuterium NMR line shapes of the PDMS sequence (soft block) reveal clearly a wide distrib

The segmental ordering within a lamellar polystyrene-polydimethylsiloxane diblock (PS-PDMS) was examined by NMR. A non-uniform stretching of the PDMS chains was evidenced. Although chain segments displaying isotropic reorientational motions are prese

The chain segment dynamics in the bulk lamellar phase of polystyrene-polydimethylsiloxane (PS-PDMS) block copolymers has been probed by NMR. The experiments were performed on a PS-PDMS diblock and on a PS-PDMS-PS triblock with twice the molecular wei

The dynamics of polydimethylsiloxane chains confined between air and a solid, wettable, and nonadsorbing surface is investigated using deuterium NMR. Chain segments in such molten films undergo uniaxial reorientations around the normal to the surface

The dynamics of deuterated poly(dimethylsiloxane) chains grafted on a solid substrate and immersed in various solvents is investigated using deuterium NMR. It is observed that the segment reorientations are uniaxial around the normal to the grafting
