Influence of intramolecular charge coupling on intermolecular interactions of polycarboxybetaines in aqueous solution and in polyelectrolyte multilayers

The present paper deals with the correlation between intramolecular and intermolecular interactions of polycarboxybetaines. degree coupling opposite charges within polycarboxybetaine molecules was varied by spacers different length substitution additional alkyl chains at quaternary nitrogen atom. In order to check polycarboxybetaines, SANS measurements were carried out aqueous polycarboxybetaines solutions. For getting information about interaction an oppositely charged polyelectrolyte, multilayers formed alternating adsorption polystyrene sulfonate (PSS) from occurrence a structure peak in spectra ability form polyelectrolyte provide indicator for character some studied Not only charge but also hydrophobicity has pronounced effect on chain conformation therefore thickness multilayers. results show that small differences molecular architecture lead interactions.
