Adsorption protocols poly

Nguyen et al. noticed that the fonnation of an adsorbed layer of poly (vinyl acetate) on aluminum, is accompanied by a reduction in the maximum water uptake, [14] see Chap. 7. This interesting switch in the hydrophobic/hydrophilic character of thin polymer layers was achieved because, upon adsorption, the increase in interfacial monomer density reduces the See volume where water can be trapped. Same as in the previous cases, this stractural transition was possible by simple thermal aimealing protocols that modify the adsorption degree. It is noteworthy noticing that these modifications occur without affecting the interfacial chemistry.
