Segmental order and dynamics of polymer chains confined in block copolymer lamellar mesophases: NMR and dielectric relaxation studies

The PDMS lamellar sublayers of a poly(styrene)-poly(dimethylsiloxane) diblock (PS-PDMS) and PS-PDMS-PS triblocks are investigated by NMR and dielectric spectroscopy. Some segments of the confined PDMS chains d...

Hole nucleation in thin diblock copolymer films

This paper reports an experimental study of a homogeneous nucleation process in the direct space, using an atomic-force microscope. Nucleated patterns are holes in a thin diblock copolymer film. The formation ...

Chain segment ordering in lamellar sublayers of block copolymers: A NMR study

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...

Monolayers of diblock copolymer at the air-water interface: the attractive monomer-surface case

We have studied both experimentally and theoretically the surface pressure isotherms of copolymers of polystyrene-polyethyleneoxide (PS-PEO) at the air-water interface. The SCMF (single chain mean-field) theor...

Coalescence in 2 dimensions: experiments on thin copolymer films and numerical simulations

This paper presents on one hand the experimental study of the coalescence kinetics of two closed bidimensional fluid domains at the surface of a multilayered dibloc copolymer film, and on the other hand a nume...

Lamellar composite magnetic materials

Synthesis of lamellar auto-assemblies of symetric PS-PBMA copolymers, doped by magnetic nanoparticles is described. As soon as particles are coated by a grafted PS layer, they can be confined in the PS layer o...

A lower critical ordering transition in a diblock copolymer melt

DIBLOCK copolymers, comprised of two distinct homopolymers covalently bonded together at one end, undergo a transition on cooling from a state in which the segments of the blocks are homogeneously mixed to one...

Dynamics of PS-PMMA diblock copolymers in toluene

The dynamic behaviour of two polystyrene-polymethylmethacrylate (PS-PMMA) diblock copolymers has been studied in toluene by quasielastic light scattering in the vicinity and above the overlap concentration C* of ...

Study of Copolymer-Homopolymer Blends

Some years ago, we started studying the structure and thermodynamics of binary and ternary copolymer-homopolymer blends. Two aspects have been developped. The first one concerns the investigation of demixing i...

Study of the structure of block copolymer-homopolymer blends using small angle neutron scattering

The structure of “dilute solid solutions” of poly(styrene-b-butadiene) diblock copolymers within a matrix of polybutadiene has been studied using small angle neutron scattering. Experimental curves exhibit sev...
