Polyol-epoxide polymers for NVH damping applications

Noise, vibration, or harshness (NVH) properties of an industrial or consumer product are reduced by incorporating therein an effective amount of a polyether- or polyester-epoxide polymer (PEEP) composition. The PEEP compositions are one-component or two-component reaction products of a polyepoxide compound and a polyol composition. The PEEP compositions have a glass-transition temperature within the range of ?50? C. to 50? C. and a loss factor of at least 0.5 by ASTM D5992 over a temperature range of at least 15 Celsius degrees at one or more frequencies within the range of 0.1 to 10,000 Hz. The PEEP compositions provide NVH damping over a broad temperature range, have improved flexibility compared with conventional epoxy technologies, avoid amine and isocyanate reactants, and can be tailored to meet target specifications.

Hydrophilic, yet slippery solid surfaces

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.
