In the synthesis of mesostructured thin films, modification or functionalization of the material can also be achieved by varying the template molecule. 

An automatic machine combining film modification by Cl with packing is shown in Fig. 2.56 [160]. 

Film Applications Polybutene-1 is used in compression packaging films, peel seal, and film modification, and to enhance the properties of polypropylene (PP) and polyethylene (PE) to make them process better, seal faster, peel with controlled force, be softer and more flexible, have better high temperature strength, or be more elastic. 

It has been established that the process of enzymatic destmction of chitosan (CHT) film specimens obtained from acetic acid solution experiences the influence of the prehistory of film formation, including the concentration of acetic acid used for films preparation and the thermal film modification. 

Surfactants function by altering the interfacial tension between the solid (particles) and liquid (surfactants). Their action as anticaking agents is not clearly understood, and various mechanisms have been proposed - protection from moisture, spreading of liqiid film, modification of crystal makeip/behavior, inhibition of dissolution and crystallization, and modification of bond tensile strength.

The improvement of the pitting resistance by aging the passive surface in the corrosive medium itself but in conditions under which no pitting occurs is also a matter of practical evidence on a much larger time scale (of the order of some months). It is believed that this improvement is due to some passive film modifications. This question forms the subject of some current work [3d]. 

Working on some industrial steels with various Cr, Ni, and Mo contents, whose sulfur content is not specified but probably contains MnS inclusions, Schmucki and Bohni [24ab] correlated the pitting resistance and the number of prepitting transients to the electronic properties of the passive film. The number of transients was found to increase with the electrode potential, up to a critical potential then to decrease, in the same way as the photoresponse of the passive layer. The number of transients is believed to increase with the concentration in deep localized electronic traps in the film. In this work, the existence of is explained by a Cr (III)/Cr(VI) transition in the passive film [24c], but it is likely that several other film modifications could be responsible for such behavior. Last, microscopic investigations revealed that sites which exhibit an enlaiged photocurrent coincide with inclusions present in the bulk material. 

A correlation between the coefficient of friction and the C ) lubricant film tri-bochemistry can be deduced frx>m these experimental results rolling pin formation produces a progressive decrease in the coefficient of friction, and the lubricant film modification corresponds to the amorphization of the C ) molecules.
