Several chemistries have been developed polydimethyl siloxane polymers (PDMS), amine- or amide-functional polydimethyl siloxanes, and silicone gum-in-cyclic blends. They are usually supplied as emulsions, offering a large choice of candidates to achieve the desired performance and physicochemical properties such as viscosity. 

Easley et al." " also provided proof-of-principle data for discrete components referred to as fluidic capacitors. While the concept of fluidic capacitance is by no means a new concept, little workhas been done to exploit this behavior in microfluidic networks. To the knowledge of the authors, only recently has there been a report that discusses the fluidic compliance of an entire microchip made up of a flexible polymer, PDMS. In this work, which was concurrent with the work by Easley...

Similarly, many reactors with integrated mixers and other functionality can be manufactured on one substrate to form, e.g., a combinatorial synthesis platform. Such microfluidic platforms may approach the complexity of VLSI electronic circuits, see e.g. [64], which gives an example fabricated by soft lithography (imprinting) in the polymer PDMS or [65], which gives an example in laser-machined laminated Mylar sheets. The combinatorial aspect of these examples consists in mixing chemicals in different ratios to achieve concentration series in a discrete way (i.e. a different concentration for each microchannel) which are subsequently used in a chemical reaction on the same microfluidic chip. 

A clear contrast between the two types of polymers, PDMS vs. PP and PA-6,6, in terms of aqueous lubricating effect is primarily due to the difference in their elasticity modulus 2 MPa for PDMS and in the GPa range for the other two (see Table 1). However, the difference in the surface roughness of the two types of polymers needs to be considered as an additional factor in determining aqueous lubricating properties. 

Work in Taiwan has centred on examination of polydimethylsiloxane (PDMS), which has unusual properties such as high dynamic flexibility, low entropy of dilution, high oxidative stability, and low glass transition temperature. The initial work was directed towards incorporating the functionalized polymer PDMS into vinyl block polymers, producing copolymers that are of considerable interest in fields such as adhesion, coating and printing.

Motivated by the importance of the stabilizer stmrture on the polymer properties, kinetics, and PSD, numerous studies have examined different types of polymers as stabilizers in SCCO2 dispersion polymerization. " In addition to fluorinated homo- and copolymers such as PFOA and its methacrylate analogue, random copolymers, block copolymers, comblike graft copolymers, and reactive macromonomers of varying molar mass and copolymer composition have been used. Fluorinated polymers and silicone polymers (PDMS) are the best choices for the portion of the surfaaant with affinity for the SCCO2 phase, while the lipophilic moieties used for the anchoring block are often chosen to be same as the monomer being polymerized.
