More complex structures formed by the Langmuir-Blodgett technique

More complex structures formed by the Langmuir-Blodgett technique 

In this chapter we turn to the study of LB films formed from polymers and LB films consisting of alternate layers of two different amphiphiles. In principle, of course, it would be possible to superimpose successive layers of three or more distinct amphiphiles but little has been done in this direction. However, a few examples of more complex alternating structures will be considered. 

Polymer LB films naturally divide into the following categories. 

Systems in which a multilayer structure is formed from molecules containing one or more double bonds and in which polymerisation is subsequently initiated by irradiation by y-rays, ultraviolet light or an electron beam. 

Systems similar to the above but in which the constituent monomers contain the diacetylene group.
