CURABLE COATING COMPOSITIONS HAVING SUPERHYDROPHOBIC, ANTI-ICING, AND ANTI-CORROSION PROPERTIES (RFT 650)

Invention Summary

Carbon fiber reinforced polymers (CFRPs) are popular in aerospace, automotive, and marine industries due to their exceptional strength-to-weight ratio and corrosion resistance. This technology features a robust duplex coating composition applied to metallic CFRP surfaces. It comprises two main layers: 1. A base layer with epoxy resin reinforced by graphene nanoplatelets (GNPs) and fullerene-C60 nanofillers; 2. A top layer of carbon nanotubes (CNTs) for enhanced properties. This system effectively seals the pores and defects typical of metallic coatings, significantly improving electrical conductivity, mechanical resilience, anti-icing, and superhydrophobic properties.

Benefits

Increased Electrical Conductivity: CNTs provide high conductivity.
Superior Water Repellency: The CNT layer creates a superhydrophobic surface.
Enhanced Anti-Icing: Delayed freezing times and reduced ice formation.
Mechanical Durability: High resistance to abrasion and external damage due to GNP and fullerene reinforcement.
Corrosion Resistance: The hybrid nanofiller provides long-term protective qualities even under harsh conditions.

Applications

Aerospace components to prevent lightening strike damage
Marine equipment requiring anti-corrosive, anti-icing surfaces
Automotive parts for superior mechanical and weather-resistance performance
