Ultrasonics Sonochemistry

Elsevier

In this study, two common industrial polymers, poly (methyl methacrylate)(PMMA) and
polystyrene (PS), were incorporated into amine-functionalized MCM-41 mesoporous silica
as reinforcement agents via an ultrasonic assisted method as a facile, fast, eco-friendly, and
versatile synthetic tool. Amino functionalization of MCM-41 were performed by 3-
aminopropyl triethoxysilane as a coupling agent and it is denoted as APTS-MCM-41. The
obtained nanocomposites (NCs), APTS-MCM-41/PMMA and APTS-MCM-41/PS, were
characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD),
scanning and transmission electron microscopies (SEM and TEM), and thermogravimetric
analysis (TGA). Their mechanical properties were also probed via stress–strain curves and
improved tensile properties were observed in the NCs relative to the neat polymers …
