Swelling experiments were performed in water at various temperatures by real-time monitoring of the decrease in pyranine (Py) and emission light intensity (I-em). The Stern-Volmer equation is modified for low-quenching efficiencies to interpret the behavior of pyranine intensity during the swelling of polyacrylamide-multiwalled carbon nanotube composites. The Li-Tanaka equation was used to determine the swelling time constants tau and cooperative diffusion coefficients D from fluorescence intensity weight and volume variations of the composite at various temperatures. It was observed that when tau decreased naturally D increased by increasing temperatures.eninfo:eu-repo/semantics/openAccessPolyacrylamideMultiwalled carbon nanotubeSwellingFluorescenceDiffusion coefficientArticle119912061333WOS:00033795690000210.1177/07316844145264382-s2.0-84902977661N/AQ2
