摘要

As part of this research, a synthesis method was developed to incorporate organophilic montmorillonite [MMT@CTA] as a dispersed filler in poly(butyl methacrylate) (PBMA) matrices using an in situ radical polymerization process in the presence of benzoyl peroxide as an initiator. The structure and interfacial interactions within the composites were carefully studied using various analytical methodologies, including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), thermogravimetry (TGA), and transmission electron and scanning electron microscopy (TEM and SEM). The results of XRD and transmission electron microscopy as well as scanning electron microscopy revealed significant changes in the surface structure and appropriate intercalation of the monomer, indicating effective incorporation into the clay structure. Thermogravimetric analyses indicate that the incorporation of MMT@CTA significantly enhances the thermal resistance of composites, thereby increasing thermal decomposition thresholds compared to unreinforced PBMA. The composite materials were also evaluated according to several properties, including water absorption capacity, moisture retention capacity, antimicrobial properties, BET surface area, and pore structure parameters. The findings show that MMT@CTA strengthens both the polymer structure and amplifies the functional properties of the composites developed.
