A thermodynamic study of F108 and F127 block copolymer interactions with liposomes at physiological temperature.

The interactions of egg yolk phosphatidylcholine liposomes with F108 and F127 triblock copolymers, in the monomer state, were analyzed by isothermal titration calorimetry (ITC) at 37 °C. According to the results, the critical micelle concentration was determined to be 0.4 and 0.

Nanohybrids of nylon 6 with multi-walled carbon nanotubes: solvent-free polymerization of epsilon-caprolactam under variable experimental conditions.

The solvent-free polymerization of epsilon-caprolactam on 1,8-diaminooctane-functionalized multi-walled carbon nanotubes (DA-MWNTs) is proposed as a simple and ecologically friendly approach to the preparation of carbon nanotubes/nylon 6 hybrid materials. The main goal of the present study was to find a minimum temperature resulting in an efficient epsilon-caprolactam polymerization, along with the optimization of the weight ratio of DA-MWNTs to epsilon-caprolactam and reaction time. The effect of temperature was studied in the range of 170 degrees C to 210 degrees C.
