Which kind of polymers do you use? It seemed to me that your polymer nanopartcles are positive charged and stick to the negativ surfaces of your plastic or glass voils.
Hi dear as you know polymerization reactions involve joining either similar or none similar monomers which react to form the polymer in question. And as you know these polymerization reactions start with an initiator which will finally lead to polymer formation in the reactor vessel so may be these products join some parts of your reaction vessel particularly if the vessel used is made of plastic, which is made from different polymers. In the other case of the involvement of glass vessels, I think it is important to consider the composition of the glass vessels because some of the glass ware materials may have in their composition some elements which can be involved in the polymerization reaction as initiators or promotors of a polymerization reaction. So it is most probable this is the cause of such sticking. I am just trying to put an interpretation or some sort of explanation to which was happening with your reactions, May be this is true or otherwise something else. Very interestingly I found your question.
Thanx Claudia ma'am...I'm using a positive polymer. I have tried to synthesized my Nps without adding iron oxide nps into it & i found that it didn't stick. But when i added iron oxide After polymer-anion salt aggregation it got stuck to voil. So in this case is there any solution?
Addition of anionic or nonionic surfactant may avoid or remove particles from walls. Even polyphosphates or polycarboxylates may work. Too low concentration will cause flocculation.
