Vermiculite in polycaprolactone films prepared with the used of ultrasound

Abstract The morphologic and phase properties of polycaprolactone/vermiculite films prepared by ultrasound intensive mixing were evaluated. Two types of the mechanically processed natural Mg - vermiculite (ball and jet milled) with different particle size and morphology and trichlormethan as an exfoliation agent were used. The polycaprolactone/vermiculite films were prepared using 1, 3 and 5 wt% of vermiculite nanofiller and were evaluated by the following methods: 3D optical confocal microscope, scanning electron microscopy, X-ray diffraction and Fourier transforms infrared spectroscopy. The positive effect of vermiculite particles on homogeneous distribution in PCL matrix was shown. The hydrophilic surfaces of each PCL film with the water contact angle in interval value of 62–74° were measured.
