Formation of Interpolymer Complexes on Polypropylene Textiles via Layer-by-Layer Modification as Revealed by FTIR Method



Oppositely-charged polyelectrolytes such poly(acrylic acid) and poly(allylamine hydrochloride) have been deposited on a polypropylene nonwoven by the layer-by-layer technique. The complex formation of this modified material has been studied by FTIR spectroscopy. It has been found that external reflectance FTIR is an efficient technique for the identification of non-complexed or complexed carboxylic groups in the modified polypropylene material.
