I have a question regarding the chemistry of the reaction between acrylamide monomers with dopamine. hcl. What happens if we add acrylamide monomers to the solution dopamine hydrochloride? Will there be the self polymerization process around the acrylamide monomers?
Dear Hamidreza Moazzeni, dopamine alone I don't think it could initiate the Polymerization. Amine may polymerize in photo- and redox polymerization of acrylamide, or may activate peroxides as well. It is possible with acrylonitrile. Acrylamide may undergo self polymerization in solution without the need to other chemical, just by heating, but uncontrable and the gel effect is more pronounced. The other catechol side of dopamine is more radical scavenging to initiate polymerization. My Regards

Other important thing. If you want to prepare a N-substituted acrylamide, react acryloyl Chloride with dopamine. My Regards
Dear Abdelkader BOUAZIZ, thanks for the hints. I know we have to initiate the polymerization process. Still, I am talking about something like grafting polydopamine to the acrylamide chains before we initiate AM's polymerization using initiators such as APS.
Dear Hamidreza Moazzeni, how are you thinking to do that ? The amide with phenol is only possible way. If you want to do a radical polymerization you have to protect the hydroxyl groups of the catechol by Forming dimethoxy ring. My Regards
Dear Hamidreza Moazzeni, I think the attached file might be interesting for you. My Regards
