Polymer micelles: an example of self-assembling polymers

Article Abstract:

A study was conducted to analyze polymer micelles. The micelles were made by the addition of a precipitating solvent for one block or direct dissolution of the dry polymer into a specific mixed solvent. The polymers supported an anthracene chromophore inserted between the polystyrene and poly(methacrylic acid) blocks. In addition, the study characterized how the self-assembling characteristics of amphiphilic polymers to form polymer micelles can be manipulated for photoredox reactions and sollubilization.

Complex charge transport in PPy/PSS films

Article Abstract:

A study was conducted to analyze the complex charge transport mechanism for polypyrrole/poly(polystyrenesulfonate) films in aqueous electrolyte solutions. The mechanism was examined using the cyclic/step electrochemical quartz crystal microbalance and the electrochemical/electrogravimetric impedance techniques. Experimental results indicated a slow charge transport process correlated with the slow electron transport process.
