Irreversibility and polymer adsorption.
Physisorption or chemisorption from dilute polymer solutions often entails irreversible polymer-surface bonding. We present a theory of the resultant nonequilibrium layers. While the density profile and loop distribution are the same as for equilibrium layers, the final layer comprises a tightly bound inner part plus an outer part whose chains make only fN surface contacts where N is chain leng...
متن کاملPolymer Translocation Induced by Adsorption
We study the translocation of a flexible polymer through a pore in a membrane induced by its adsorption on trans side of the membrane. When temperature T is higher than Tc, the adsorption-desorption transition temperature, attractive interaction between polymer and membrane plays little role in affecting polymer conformation, leading to translocation time that scales as τ ∼ L3 where L is the po...
متن کاملPolymer adsorption on colloidal particles
2014 We consider the adsorption of polymers on colloidal particles 2014 spheres and cylinders 2014 whose dimensions are comparable to solution polymer radii of gyration. Adsorption occurs if the « sticking energy » per monomer exceeds a certain threshold. For a colloidal particle, this threshold increases by an amount inversely proportional to its radius. In addition, the repulsive interactions...
متن کاملAdsorption of polydisperse polymer chains
The adsorption of polydisperse ideal polymer chains is shown to be sensitive to the large N tail of the distribution of chains. If and only if the number of chains decays more slowly than exponentially then there is an adsorption transition like that of monodisperse infinite chains. If the number decays exponentially the adsorption density diverges continuously at a temperature which is a funct...
متن کاملAdsorption Theory for Polymer Molecules
well as polymer and surface. See, for example, the definition of E preceding Eq. (40) of FH-2. In the plateau region, on the other hand, adsorption was predicted to be molecular weight independent. Considering the approximations involved, it would probably be more realistic to simply assert that molecular weight dependence is small. The predicted increase in the adsorption plateau with increasi...
