Flexural deflection as a measure of van der Waals interaction
forces in the CNT array.
vdw] is the non-bonded van der Waals interaction
In the calculation, the Hamaker constant for the particle-wall van der Waals interactions
was chosen as 0.
Obviously, van der Waals interaction
between the molecules was also included.
Because of their chemical makeup, both substances should have had similar degrees of van der Waals interactions
with the geckos' setae, and therefore the animals should have clung similarly to both surfaces, Izadi says.
Ionic liquids are salts with melting points below 100 degrees Celsius, and represent a new class of non-molecular liquid materials with unique property profiles due to a complex interplay of Coulombic, hydrogen bonding, and van der Waals interactions
