Summary: This study investigated the effects of UV light irradiation on multiwall-carbon-nanotube reinforced poly(methyl methacrylate) composites, focusing on changes in glass transition temperature and mechanical properties. The addition of MWCNTs increased the glass transition temperature of the composites, but UV irradiation negatively affected the properties. The research presented a simple equation to calculate the effective modulus of the composites and found that toughness and elongation were higher in composites without UV irradiation.

Summary: The study investigated the thermal, mechanical, and water uptake properties of epoxy nanocomposites with surfactant-modified MWCNTs, showing that the addition of surfactant-modified CNTs into the epoxy significantly improved mechanical and thermal properties. However, excessive concentration of CNTs led to agglomeration and decreased the performance of the nanocomposites.

Summary: This study successfully obtained electrically conductive materials by adding functionalized multiwalled carbon nanotubes, and confirmed that carbon nanotubes as polymer reinforcements can increase tensile strength and strain percentage. However, increasing nanofiller percentages resulted in a drastic decrease in Young's modulus values.

Summary: In this study, an electrochemical sensor for the determination of BHA was developed by electropolymerization of OC over MWCNTs. The POC/MWCNTs electrode showed BHA oxidation occurring at 0.27 V, with a linear detection range from 0.33 mu M to 110 mu M and a detection limit of 0.11 mu M. Amperometric determination of BHA using chronoamperometric techniques confirmed the linear relationship. The real-time analysis of sensors was validated by analyzing packed potato chips samples.

Summary: This study investigates the mechanical characterization of carbon fiber reinforced polymer laminates reinforced with non-treated and treated multiwalled carbon nanotubes using nitric acid. The results show that treated CNTs lead to improved flexural strength and interlaminar shear failure stress compared to control laminates, while longer mixing times may have a detrimental effect on mechanical properties.

Summary: In this study, epoxy acrylate/nickel-plated carbon nanotubes composites with different structural orientations (X, Z) were prepared using digital light processing 3D, and the effect of nickel-plated carbon nanotubes orientation in a magnetic field on the mechanical properties of the composites was systematically investigated. Scanning electron microscopy revealed the orientation of the fiber in the magnetic field. The experimental results demonstrated significant anisotropy in the mechanical properties and friction coefficient of the material, but the anisotropy in wear rate was not significant. The X sample exhibited approximately 18% higher tensile strength than the Z sample at a nickel-plated carbon nanotubes content of 0.15 wt%. Moreover, the X sample showed approximately 15% higher impact strength than the Z sample at a Ni-MWNTs content of 0.1 wt%. The friction coefficient on the (X, Y) plane was about 20% lower than that on the (Y, Z) plane at a carbon nanotubes content of 0.05 wt%.
