摘要：
A new procedure for processing of epoxy/polyamide blend was explored via solution polymerization of epsilon-caprolactam in N-methylpyrollidone (NMP), which resulted in a suspension of nylon-6 in solvent at room temperature. The suspension was blended with water based epoxy resin using mechanical stirring at room temperature. Several films were prepared from blend by varying the amount of nylon-6 without curing agent. All films were fully characterized for thermal and dynamic mechanical properties using differential scanning calorimetry and dynamic mechanical analysis. The addition of nylon-6 had a plasticizing effect on epoxy evident by decrease in glass transition temperature (T-g). The reaction between nylon-6 and epoxy was studied using Fourier transform infrared spectroscopy by following the characteristic epoxy peak (914 cm(-1)). The growth of nylon-6 crystals in epoxy matrix lead to spherulitic multiphase morphology, which was observed under scanning electron microscope. (c) 2013 Wiley Periodicals, Inc. J. Appl. Polym.
