Summary: Initiated chemical vapor deposition (iCVD) is a dry method for designing organic and hybrid polymers, which provides conformal surface modification over intricate geometries. iCVD films can be grown with uniformity, high-purity, and pinhole-free properties, and can be applied onto flexible substrates, 2D materials, and liquids. The functional groups in iCVD polymers offer fine-tuning of surface energy, surface charge, and responsive behavior. iCVD polymers have various morphologies, such as nanostructured surfaces, nanoporosity, and shaped particles, and they are widely used in sensing, electronics, optics, electrochemical energy storage, and biotechnology applications.

Summary: The catalytic activity of K10 montmorillonite during the CVD of carbon nanotubes was investigated, and the influence of free iron on CNT synthesis was studied. Before Fe removal, K10-Mt was covered with pyrolytic carbon deposits, while after purification, regular forms of CNT were formed. Multi-walled carbon nanotubes were observed on the surface of pure K10-Mt, and after extraction of free iron, nucleation sites for CNT growth were identified.

Summary: This study used novel joint treatments to strengthen carbon fiber reinforced polymer (CFRP) composites. Vertically aligned carbon nanotubes (VACNTs) were grown in situ on the catalyst-treated CF surface using the chemical vapor deposition (CVD) method, forming an integrated structure. The resin pre-coating (RPC) technique was further employed to eliminate void defects and enhance the flexural strength of the CFRP composites. The results showed significant improvement in flexural strength and change in failure mode with the joint treatments.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.

Summary: Faster heating rates and higher process temperatures can reduce the total process time while achieving the same degree-of-cure. Thermal analysis shows that thermoplastic interleaf particles melt at the recommended curing temperature. A short dwell at a lower temperature can prevent the mixing of thermoplastic particles and thermoset pre-polymer.

Summary: In response to the global environmental pollution crisis caused by waste plastics, recyclable design is an effective solution. A CPVC/PUA nanocomposite foam was developed using the plasticizing-foaming-reinforcing strategy, combined with catalytic carbonization. The foam exhibited high expansion ratio, robustness, solvent resistance, flame-triggered shape memory effect, and ablation resistance. The foam could be directly upcycled into functional carbon foam with attractive electromagnetic interference shielding performance.
