Brillouin 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 کاملTechnology of Polymer-cement Mixes Preparation with Specified Rheological Properties Technology of Polymer-cement Mixes Preparation with Specified Rheological Properties
In recent years, many new materials appeared on our construction market: polymer pastes, sealants, primers, foam. In addition, dry mixes have been suffered some changes. Previously, for the bonding of stones, leveling and processing of walls and ceilings lime, clay, alabaster, gypsum, and mixtures were used. Before the use, they are diluted with water. The development of dry mixes conducted in ...
متن کاملSelf-Oscillating Structural Polymer Gels
Self-oscillating polymer gel has become a distinguished class of smart soft materials. Here we fabricated and demonstrated a self-oscillating structural gel network with the incorporation of the Belousov-Zhabotinsky (BZ) reaction. The structural polymer gel oscillates at a macroscopic level with remarkably faster kinetics compared to a normal gel of similar chemical compositions. The structural...
متن کاملHigh internal phase emulsion gels (HIPE-gels) from polymer dispersions reinforced with quadruple hydrogen bond functionality.
A convenient route to organogels templated by high internal phase emulsions has been developed. Key is the use of a waterborne polymer latex loaded with a multiple hydrogen bond (MHB) functionality that becomes disentangled and transfers across the oil-water interface forming a gel network in the oil phase via hydrogen bond interactions.
متن کاملScattering from dilute ferrofluid suspensions in soft polymer gels.
Small angle neutron and x-ray scattering methods are used to investigate the structure of dilute suspensions of two different ferrofluid systems dispersed in soft polyacrylamide hydrogels. It is found that the particles in the fluid are fractal aggregates composed of smaller particles of radius ca. 5 nm. The fractal dimension is strongly dependent on sample, taking the value 1.7 in the first sa...
