“…Figure a shows the 1 H NMR spectra of cardol. The characteristic peaks of protons at each location of cardiac phenol are listed below: peak 1 corresponds to the protons in the phenolic hydroxyl group; peaks 2–3 correspond to the protons on the benzene ring; and peaks 4–10 correspond to the protons on the carbons in the side chain Figure b shows the 1 H NMR of PE-Cardol.…”

“…For each measurement 1 mL of resin formulation was applied on the lower plate of the rheometer for 5 s before the upper plate was moved downward to adjust the gap to a thickness of 0.045 mm. Each measurement was repeated three times, with a recovery period between each run, and the following parameters were kept constant: shear rate from 1 to 1000 s − 1 at 20°C for 120 s [20].…”

Objectives To analyze the incorporation of cardanol trimethacrylate monomer (CTMA), derived from the cashew nut shell liquid, as a substitute for Bis-GMA on the physicochemical and mechanical properties of experimental resin composites. Materials and Methods The intermediary cardanol epoxy was synthesized via cardanol epoxidation, followed by synthesis of CTMA through methacrylic anhydride solvent-free esterification. Experimental resin composites were formulated with an organic matrix composed of Bis-GMA/TEGDMA (50/50 wt %) (control). CTMA was gradually added to replace different proportions of Bis-GMA: 10 wt % (CTMA-10), 20 wt % (CTMA-20), 40 wt % (CTMA-40), and 50 wt % (CTMA-50). The composites were characterized in terms of degree of conversion, water sorption and solubility, viscosity, thermogravimetric analysis, dynamic mechanical analysis, flexural strength and elastic modulus. Data were analyzed with one-way ANOVA and Tukey's post-hoc test (α = 0.05), except for water sorption data, which were analyzed by Kruskall-Wallis and Dunn’s method. Results CTMA-based and control composites did not show statistically significant differences regarding degree of conversion, flexural strength and elastic modulus. CTMA reduced the viscosity and solubility compared to Bis-GMA-based composite. The CTMA-40 and CTMA-50 exhibited significantly lower water sorption compared to the control. Also, acceptable thermal stability and viscoelastic properties were obtained for safe use in the oral cavity. Conclusions The incorporation of CTMA into composites resulted in similar chemical and mechanical properties when compared to Bis-GMA-based material, while reducing viscosity, water sorption and solubility. Clinical Relevance CTMA could be used as a trimethacrylate monomer replacing Bis-GMA in resin composites, thereby minimizing BPA exposure.

“…There are different types of epoxy resins, such as bisphenol A diglycidyl ether, cycloaliphatic epoxy resins, trifunctional epoxy resins, and tetrafunctional epoxy resins [118]. The global commercialization of epoxy resins market reached USD 25.8 billion in 2018, and for the year 2022 it is estimated to be around USD 34 billion [119]. Among these, bisphenol A diglycidyl ether is the most widely used in the coating industry due to its low cost and many desirable properties such as hardness, gloss and chemical resistance.…”

Trends on Reinforced Polymer Composites – A Review

et al. 2022

View full text Add to dashboard Cite

In recent years, the interest in using fiber reinforced composites (FRC) has increased due to their potential to replace traditional materials in various applications. The advantages of polymer composites from natural fibres are: biodegradability, high performance, market availability and low price. This article is based on a review that discusses both polymer composite materials and typical applications by other authors on fiber reinforced composites (FRCs).
