Summary: This study investigates the effects of compositional variations and processing parameters on the properties of epoxy-based composites filled with carbon nanomaterials. The study found that the percolation threshold of carbon nanotubes (CNT) was 0.1 wt% and high power ultrasonication had a detrimental effect on the electrical and flexural properties. Increasing resin viscosity resulted in higher void content, which negatively affected the mechanical and viscoelastic properties.

Summary: This study investigates the CNT penetration phenomenon in the VI process by measuring electrical conductivity. The effects of resin temperature, CNT content, and processing technique on composite laminate quality were examined by monitoring electrical properties. Composites with various CNT contents were also manufactured using compression moulding and vacuum bagging for comparison. Results showed that electrical conductivity measurement was an effective tool for assessing CNT penetration in VI. Higher CNT contents led to resistive and capacitive behavior, but increasing the epoxy/CNT temperature improved CNT penetration.

Summary: In this study, the capability of Terahertz spectroscopy for determining the thermal properties of phase change materials (PCM) in an acrylated polyurethane coating was investigated. Spherical shaped mesoporous silica materials (MPSs) were used as a template for stearic acid (SA) and SA was impregnated into MPSs to investigate its PCM properties. The thermal properties of the resin were determined using both conventional Differential Scanning Calorimetry (DSC) and Terahertz Time Domain Spectroscopy (THz-TDS), showing that THz Spectroscopy is a strong technique for characterizing phase changing materials.

Summary: The dispersion of cellulose nanocrystals (CNC) within polybutylene adipate terephthalate (PBAT) was investigated in this study. PBAT/CNC nanocomposites with different CNC contents were prepared through solution casting and dilution of a solution casted masterbatch using a twin screw extruder. The efficiency of the two preparation approaches on CNC dispersion was evaluated through transmission electron microscopy and rheological analysis. The results showed that solution casted PBAT/CNC nanocomposites had better CNC dispersion compared to their melt processed counterparts, while the diluted melt processed cases also exhibited good CNC dispersion. As a result, CNC was able to form a percolation network within PBAT at CNC contents of around 2 and 4 wt% in the two approaches, respectively.
