For the first time, a porous mesh of poly(ε-caprolactone) (PCL) was electrospun directly onto carbon fiber (CF) plies and used to develop novel structural epoxy (EP) composites with electro-activated self-healing properties. Three samples, i.e.

Article Synopsis
  • Thin cyclic olefin copolymer (COC) foils were used as healing agents in carbon fiber-reinforced epoxy laminates, where they were placed between layers during fabrication.
  • Introducing COC layers reduced fiber volume and increased porosity, leading to decreased mechanical properties of the laminates due to poor adhesion with the epoxy.
  • Thermal healing of the specimens showed that laminates with 44 μm and 77 μm COC layers achieved healing efficiencies of 164% and 100% respectively, while the neat laminate without COC had only 2% efficiency, highlighting the COC's effectiveness as a healing agent.

Cyclic olefin copolymer (COC) particles were dispersed in various amounts in an epoxy matrix, and the resulting blends were used to impregnate unidirectional carbon fibers (CF) by hand lay-up. The thermal stability was not substantially modified by the presence of COC particles. The mixture of the two polymers resulted in a phase separated blend and the flexural modulus and interlaminar shear strength progressively decreased with the addition of COC particles in the laminates.

Accurate elucidation of genome wide protein-protein interactions is crucial for understanding the regulatory processes of the cell. High-throughput techniques, such as the yeast-2-hybrid (Y2H) assay, co-immunoprecipitation (co-IP), mass spectrometric (MS) protein complex identification, affinity purification (AP) etc., are generally relied upon to determine protein interactions.
