  • Patent number: 10442166
    Abstract: In this work, a hydrophilic, yet slippery solid surface was developed. Because the surfaces are hydrophilic, there is significant affinity between the surface and contacting water, which results in substantial spreading of the contacting liquids on the surface. Due to their strong affinity, a high solid-liquid adhesion having virtually no mobility of the water on the surface occurs. However, counter-intuitively, the disclosed surfaces are highly slippery such that liquids can slide on the surface while maintaining their hydrophilicity. Demonstrated herein are water droplets that can slide on the surface under its own weight, when the hydrophilic, yet slippery solid surface is slightly tilted (?=3°). This indicates that the disclosed hydrophilic surfaces are slippery to water.

  • Patent number: 10400074
    Abstract: The present invention relates to the development of carbon fiber carbon nanotubes reinforced polymer composites for high strength structural applications. It is very difficult to incorporate higher amount of carbon fiber >60 vol % in any of the polymer matrix. Beyond this loading the mechanical properties of these composite starts deteriorate. Therefore, further improvement in the mechanical properties is not possible. Herein, a novel method is developed to fabricate the hybrid carbon fiber epoxy composites reinforced with multiwalled carbon nanotubes. The flexural strength of the hybrid composites (˜45 vol % CF+CNT) was achieved more than 600 MPa which is more than 35% over pure carbon fiber/epoxy composites (˜50 vol % CF). These high strength hybrid composites can be used in wind mill blades, turbine blades, sport industries, automobile and airframe.
