Silicone Rubber Tack II: The Time-Dependent Autohesion for Symmetric Rubber–Rubber Contacts

The autohesion data are gathered for poly(dimethyl siloxane) (PDMS) with different molecular weights. The influence of molecular weight of the polymer is very pronounced. The data are interpreted on basis of the Wool-deGennes reptation theory; the application of first order kinetics of wetting is also tested. PDMS with a molecular weight only partially permitting the formation of entanglements exhibits a remarkably different and unusual behavior compared with the high molecular weight polymers. The latter develop tack in the form of logarithmic type curves, while the former show the presence of local maxima in the tack-time curves.

Preparation and Characterization of Silicone Rubber Membrane

Pervaporation membrane with preferential permeation for organic compounds over water was prepared and characterized. Selection of membrane material and the effects of polydimethylsiloxane (PDMS), cross-linker, and catalyst concentrations on performances of pervaporation membrane at room temperature were discussed. In addition, the time of cross-linking, and the kinds of basic plate in the process of preparation were tested. The formulation of pervaporation membrane material was determined. Through the characterization of membrane by infrared spectrometry(IR), scanning electron microscopy(SEM), transmission electron microscopy(TEM) and X-ray diffraction(XRD), it is proved that the structures and characters are suitable for the pervaporation process. Experiments also demonstrate that the permeate flux and separation factor are suitable for the process.
