SANS from Pluronic P85 in d-water

December 1, 2010
Author(s)
Boualem Hammouda
Small-angle neutron scattering (SANS) has been used to investigate pluronic P85 (EO 26PO 40EO 26) copolymer in deuterated water. A range of P85 fractions were measured for a wide sample temperature window. A rich phase behavior is reported. Unimers were

Clustering prevails in water-soluble polymers and biological macromolecules. It has also been observed in polar solvent mixtures. The possible causes of clustering are discussed. A systematic investigation of clustering in poly(ethylene oxide)/d-water

SANS from P85/Water-d Under Pressure

Author(s)
Bryna Clover, Boualem Hammouda
Pluronics are triblock copolymers of PEO-PPO-PEO. Pluronic P85 forms a rich phase behavior when dissolved in water. Unimers are observed at low temperature while micelles form at higher temperatures. Spherical, cylindrical and lamellar micelles are
