Estudou-se a interação do polímero poli (N-isopropilacrilamida), PNIPAM, com surfatantes iônicos utilizando a técnica de titulação calorimétrica e temperaturas na faixa de 17 a 29°C. Para tal estudo foram utilizados um surfatante aniônico, o dodecil sulfato de sódio, SDS, e três catiônicos, brometos de dodecil e hexadeciltrimetilamônio, DTAB e CTAB, e cloreto de dodecilamônio, DAC. A técnica empregada é muito sensível e permite a determinação precisa dos parâmetros que caracterizam a interação polímero-surfatante. Através dos resultados obtidos é possível concluir que a interação do polímero PNIPAM com surfatantes iônicos é fortemente influenciada pela temperatura. Esse comportamento pode ser atribuído à mudança na hidratação da cadeia poli...
