Özet

In this study, the synthesis of N-doped C-dot embedding poly(N-isopropylacrylamide) (p(NIPAAm)) particle composites via surfactant-free emulsion polymerization technique was reported. The fluorescent property of N-doped C-dot combined with thermo-responsive properties of p(NIPAAm) particles (p(NIPAAm)/C-dot) render smart materials with intriguing properties. The particle size and volume phase transition temperature (VPTT) values of p(NIPAAm) based particles was altered in accord with the amount of embedded N-doped C-dot within p(NIPAAm) particles between 1,000-750 nm and 35.4-37.2 degrees C, respectively. On the other hand, N-doped C-dot within p(NIPAAm) particles was afforded fluorescent properties with emission peak at around 460 nm. The effect of the amount of N-doped C-dot within p(NIPAAm) particles, temperature and pH were investigated on the fluorescent properties of N-doped C-dot embedded p(NIPAAm) particle composite. POLYM.
