Amphiphilic Stackable Gels Synthesized by Atom Transfer Radical Polymerization

Favoritar este trabalho

The synthesis of multilayered stackable gels based on DMAEMA and BMA was performed using ATRP to combine layers with different properties. A pre-gel solution was introduced on top of a previously synthesized gel, and these new components then underwent ATRP to form the subsequent layer. In general it was shown that two layers sequentially synthesized by ATRP cannot be connected if immiscible solvents are used to synthesize each gel. Successfull strategies to overcome these factors are presented.
