Summary: Fiber-reinforced polymer composites, especially carbon fiber-reinforced epoxy (CFRE) laminates, have been widely used in the aircraft and aerospace industry. The interface between the matrix and fiber plays a critical role in determining the overall structural properties of CFRE laminates. In this study, electrophoretic deposition (EPD) was used to deposit covalently coupled multiscale graphene oxide (GO)/carbon nanotube (CNT) nanoconstructs onto carbon fiber (CF) fabric, resulting in improved flexural strength and interlaminar shear strength compared to the neat CFRE. The deposition of GO/CNT nanoconstructs improved the performance of CFREs by enhancing wettability, surface free energy, and surface roughness.

Summary: This research aims to design and study a mechanical recycling process for the reuse of carbon fibers and CFRP composites. The process involves reducing the length and width of the materials, obtaining rods, and reintegrating them into a polymeric matrix as fillers. Preliminary studies are conducted with various lengths of continuous and discontinuous unidirectional fibers, followed by optimization of processing conditions including reinforcement length, plasma surface treatment, and resin post-curing. The resin is thermally characterized using differential scanning calorimetry (DSC), and the composites are mechanically characterized using tensile strength tests and factorial design. The composites are also observed through scanning electron microscopy (SEM) to study fracture mechanics. Optimal processing conditions have been identified, reducing the reinforcement length to 40 mm while maintaining the mechanical properties of continuous reinforcement. Additionally, post-curing of the epoxy resin matrix is required, but low-pressure plasma treatment (LPPT) is not recommended for the reinforcement.

Summary: Controlling the surface chemistry of elastomers, such as PDMS, is crucial for various applications. However, achieving nanostructured chemical control on amorphous material interfaces below the length scale of substrate heterogeneity is not easy, and is particularly challenging to separate from changes in network structure. A new method for precisely structured surface functionalization of soft materials, including PDMS, has been developed, maximizing steric accessibility. This provides a foundation for generating nanometer-scale functional patterns on PDMS with varying elastic moduli, which is important for applications like cell culture.

Summary: We propose a method to determine the temperature-dependent properties of the SYTO-13 dye bound to DNA using fluorescence measurements. Through mathematical modeling, control experiments, and optimization, we can separate the dye binding strength, brightness, and experimental noise. By focusing on low-dye coverage, the model avoids bias and simplifies quantification. Utilizing the temperature-cycling capabilities of a real-time PCR machine increases throughput. The computed properties for single-stranded DNA and double-stranded DNA are consistent with intuition and explain the enhanced fluorescence of the dye in the presence of double-stranded DNA compared to single-stranded DNA.

Summary: Cellulose nanocrystal (CNC) thin films are sustainable materials with anisotropic mechanical properties. The fracture mechanisms and modulus of CNC films are found to be dependent on particle alignment with respect to the loading direction. A new experimental method was developed to measure the mechanical anisotropy of thin CNC films by observing the wavelength of wrinkles formed during uniaxial tensile strain. The elastic modulus of CNC films decayed exponentially with increasing misalignment angle to the loading direction, and the fracture mechanism was observed to depend on the misalignment angle through coarse-grained modeling.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
