Formation of a "hard microemulsion" and its role in controllable synthesis of nanoparticles within a functional polymer matrix.

Qingli Qian et al.

Langmuir : the ACS journal of surfaces and colloids, 28(1), 736-740 (2011-11-15)

Microemulsions are often used in the synthesis of nanoparticles in solution. In this work, we put forward the concept of a "hard microemulsion", which is based on the differential partitioning of water and ethanol solvent molecules inside functional polymer matrices.
