Small-angle neutron scattering on polymer gels: phase behavior, inhomogeneities and deformation mechanisms
Recent developments in small-angle neutron scattering (SANS) investigations on polymer gels are reviewed by encompassing (i) volume phase transition and microphase separation, (ii) inhomogeneities in polymer gels, (iii) pressure dependence of hydrophobic interaction and (iv) structural characterization of super-tough gels. These developments owe much to the understanding of gel inhomogeneities ...
متن کاملOrganization of surfactant micelles adsorbed on a polymer molecule in water : a neutron scattering study
2014 Complex particles are formed in water by the spontaneous association of poly(ethylene oxide) macromolecules (PEO) with the small amphiphilic molecules of sodium dodecylsulfate (SDS). As a result, the phase diagram of dilute PEO + SDS solutions shows 2 singularities : a critical SDS concentration for the formation of the aggregates, and a stoichiometry. Small angle neutron scattering experi...
متن کاملBrillouin light-scattering from polymer gels
The experimental results of the Brillouin shift and width for poly(vinyl alcohol) and poly(vinyl chloride) gels as a function of gel network volume fraction have been analysed using the theory of Marqusee and Deutch for Brillouin light-scattering from polymer gels, incorporated with a new plausible assumption relating the speed of sound in the gel network with its volume fraction. It has been f...
متن کاملComplementary use of small-angle neutron scattering and dynamic light scattering studies for structure analysis and dynamics of polymer gels
Small-angle neutron scattering (SANS) and dynamic light scattering (DLS) have been complementarily employed in order to investigate the structure and dynamics of slide-ring (SR) gels, a class of novel polymer gels having advanced mechanical properties. SR gels consist of long flexible polymer chains and movable cross-links along the polymer chain. It is demonstrated that complementary use is ne...
متن کاملOsmotic and Small-angle Neutron Scattering Properties of Dna Gels
Introduction In general, the description of polyelectrolyte systems (solutions and gels) requires a formalism that can take into account the existence of the multiple length scales that characterize the structure and reflect changes in the thermodynamic interactions. In the presence of high valence cations DNA undergoes a volume transition. The aim of the present study is to identify the main s...
