Question
(c) A linear hydrophilic polymer was added to a suspension of nano-size particles with 20 nm radius
in water. The polymer in water adopts a coil structure with a radius 10 nm. Explain the nature of
the interparticle force introduced by the addition of the polymer, describe the effect of temperature
on the force and the expected range (in nm) of the force if
the polymer does not bind to the surface of the particles,
one end of the polymer is anchored to the surface of the particles.
