Zircon‐filled poly(methyl methacrylate) (PMMA) composites were synthesized, and their physical properties after ambient heat treatments were investigated. The sub‐micron zircon filler was obtained by purifying local zircon sand. The heat treatments were at 25°C (untreated), 55°C, and 70°C, around the glass transition temperature of PMMA. The crystal and molecular structures of the samples were investigated using X‐ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The thermomechanical, optical, and thermal (between RT and 550°C) properties of all composites were examined using dynamic mechanical analysis (DMA), UV–Vis spectroscopy, and differential thermal/thermogravimetric analysis (DT/TGA) instruments. XRD patterns showed that there were no crystal structure changes. FTIR peaks were reduced due to the heat treatment indicating the presence of PMMA molecular degradation in the heat‐treated samples. Meanwhile, DMA data showed that the heat‐treated samples exhibit a much lower room temperature storage modulus, that is, up to half as compared to the untreated ones. Furthermore, the heat treatment also affects the optical properties, including a slight drop of transmittance in UV‐A and visible regions but a slight increase of transmittance in UV‐B and UV‐C regions. Finally, the differential scanning calorimetry/thermogravimetry (DSC/TG) data show that the heat‐treated pure PMMAs become more challenging to undergo thermal degradation (i.e., mass drop).

“…PMMA is characterised by high transparency in the visible spectrum, and good thermal and mechanical strength. It is widely used in different applications like optoelectronics, micro-photonics, as an alternative for glass in solar cells, optical lenses, UV photolithography, ion-beam lithography, diffractive optics devices (Bao et al 2006) and as a host material with different nanoparticles for different applications, like gamma-ray shielding performance (Cao Da et al 2020) and shielding purposes from UV photons and its optical applications (Rishi Pal Chahal et al (2015); Rishi Pal Chahal et al (2016)), in dosimetry (Beigzadeh, Rashidian Vaziri (2021), Abdullahi et al 2022), in alpha particle detection (Chhangani et al 2021). Due to the growing demand for manufactured polymeric materials, the improvement of its properties should be investigated using a variety of methods.…”

Polymeric materials are macromolecules, essentially a combination of numerous repeated subunits. Polymers are innovative and advanced materials that currently have a strong impact on our daily lives. In recent years, polymer use has been prominent due to the materials’ distinctive properties; thus, they entered different fields of science, technology and industrial-biomedical applications.The improvement of photoluminescence, optical and electrical characteristics of non-conducting Poly(methyl methacrylate) (PMMA) films was studied. Upon gamma irradiation of various doses, the photophysical and electrical properties of PMMA films were investigated using photoluminescence spectroscopy, ultraviolet–visible (UV-Vis) spectroscopy and the LCR Meter Bridge Circuit technique. The fluorescent response improved the photoluminescence (PL) spectral emission peaks according to gamma values. Strong fluorescence peaks appeared with the highest gamma dose. The UV–Vis results revealed a significant red-shift in the absorption edge as gamma doses increased. This shift exhibits a continuous decrease in the energy band gap values (from 3.50 to 2.60 eV for direct transition and from 3.05 to 1.55 eV for indirect transition). This was due to the formation of carbon clusters, which led to an increase in the electrical conductivity and improved the dielectric parameters of the irradiated PMMA films. Among a variety of measurements presented and discussed in the present study, the electrical measurements showed improved electrical characteristics of gamma-irradiated PMMA films.
