“…The fact that, for our biomaterial, the minimal concentration to observe antimicrobial effects was lower than the concentrations reported to produce similar materials could be explained by the 3D-printed methodology that was used for the preparation of the graphene–PMMA specimens. In fact, several studies showed the high potentiality of this methodology for the preparation of new polymeric biomaterials with enhanced antimicrobial activity [ 43 , 44 ]. It is worth mentioning that a high degree of dispersion of nano graphene platelets in the resin is required for a successful 3D printing, which in turn is expected to potentiate its antimicrobial activity.…”

The present study aimed to test, in vitro, the antimicrobial activity against Candida albicans and Streptococcus mutans and the surface roughness of a 3D-printed polymethylmethacrylate dental resin enhanced with graphene. A 3D-printed polymethylmethacrylate dental resin was reinforced with four different concentrations of graphene: 0.01, 0.1, 0.25 and 0.5 wt%. Neat resin was used as a control. The specimens were printed in a liquid crystal display printer. Disc specimens were used in antimicrobial evaluation, and bar-shaped specimens were used to measure surface roughness. The study of antimicrobial activity included the inhibition of the growth of C. albicans and S. mutans and their adhesion to the resin’s surface. Surface roughness increased with the increase in the graphene concentration. The growth inhibition of C. albicans was observed in the different concentrations of graphene after 24 h, with no recovery after 48 h. The specimens doped with graphene were capable of inactivating S. mutans after 48 h. The surface-adhesion studies showed that the density of microbial biofilms decreases in the case of specimens doped with graphene. Graphene, despite increasing the resin’s surface roughness, was effective in inhibiting the growth and the adhesion to the resin’s surface of the main inducers of prosthetic stomatitis.

The viscosity of the polymer melt has an impact on both the processing and properties of the product. However, conventional viscosity measurement methods have limitations such as strict testing conditions, large sample sizes, and long response times. This paper proposes a simplified method that utilizes differential scanning calorimetry to determine the viscosity–temperature relationship of the polymer melt. The research subjects consist of four noncrystalline polymers and five crystalline polymers. A new thermodynamic fragility formula of crystalline polymer is obtained. Additionally, high‐temperature limiting viscosity shows a good linear relationship with fragility. Compared with the traditional viscosity measurement, this method is a simpler and more effective way to model the viscosity of polymer melt and has broad prospects in application.

In this work, using the spin coating method to create polyvinylidene fluoride (PVDF)/polyethylene oxide (PEO) thin films, the effects of nano-tungsten oxide (WO2) doping were investigated. The novelty of this research lies in its investigation of varying weight concentrations of WO2 nanoparticles (NPs) within the composite films. Comprehensive characterization techniques were employed, including structural analysis via X-ray diffraction (XRD), which revealed a clear and prominent peak in the XRD of the PVDF/PEO films, and the films' polycrystalline nature with tetragonal structures. The grain size was noted to increase with higher WO2 NPs doping. Field emission scanning electron microscopy (FE-SEM) showed hexagonal-like α-phase PVDF crystals and uniform distribution of WO2 NPs. Furthermore, Fourier-transform infrared spectroscopy (FTIR) confirmed the characteristics of PVDF/PEO and identified specific doping compounds, confirming successful incorporation. The optical transmittance spectra unveiled the films' optical band gap energy, optical transition types, and absorption characteristics, where novelty emerged as the band gap energy significantly increased from 3.0 eV to 3.64 eV with an increased WO2 NPs weight doping percentage, signifying profound electronic structure modifications and potential applications in optoelectronics and sensors.
