Resumo: | The study of the degradability of PA6 / organoclay nanocomposites was evaluated to
minimize the effects of plastic waste in the environment. The use of clays usually accelerates the
degradation of nanocomposites. A regional clay (polyamide 6, Polyform - B300) and a quaternary
ammonium salt (Cetremide (hexadecyltrimethyl ammonium bromide) were used. The hybrids were
obtained in a co-rotating twin screw extruder and the tensile and the impact specimens were
obtained through injection. The infrared spectroscopy (FTIR) and the X-ray diffraction (XRD)
confirmed the presence of the salt molecules in the modified bentonite and its organophilization.
The XRD results of the hybrids indicate that the peak of the organophilic clay disappeared when
incorporated into the polyamide, showing that all systems were exfoliated and/or partially
exfoliated structure. The nanocomposites showed higher tensile mechanical properties when
compared to the properties of pure polyamide, and the various conditions of aging influenced the
degradation of these materials |
