Abstract
Novel clay/waterborne polyurethane (WPU) nanocomposites were synthesized in which the clay was acid-modified with hydrochloric acid. The molecular motion of nanocomposites was investigated using high resolution solid state 13C NMR technique. Addition of clay drastically decreased the molecular mobility of waterborne polyurethane in hard segment; but little in soft segment. Two-leg trouser studies revealed that introducing clay into waterborne polyurethane significantly enhanced the tearing toughness of the nanocomposites.
