Chain dipping lines

Figure 4.8 Chain dipping lines in a medical glove manufacturing factory.

Figure 6 Effect of alkyl-chain length of aliphatic acid cadmium salts monolayers, [CH3(CH2) .2COO-]2 Cd, on the amount of incorporated water (W2) and the evaporation speed of the water (v). The broken line is calculated from eq. (3). (surface pressure 30 mN m-i, dipping speed 100 mm min-1, 20 °C, at the 5th dipping cycle).

Fig. 5. Schematic of Langmuir-Blodgett transfers. The gray circles represent the hydrophilic head groups, and the thin black lines represent the alkyl chains. The molecules have been spread on an aqueous subphase, (a) A hydrophilic substrate is being withdrawn from the dipping well and is attracting the hydrophihc head groups that drive the film transfer, (b) A hydrophobic substrate is being pushed down through the monolayer. The alkyl chains are transferred, and the monolayer is pulled off the surface by hydrophobic interactions.
