“…PDMS oligomers mix readily with alkoxide‐based metalorganics, which can be copolymerized by hydrolysis and polycondensation in the presence of water into bioactive apatite‐forming bulk materials,32 elastic particles with nanodomain heterostructures,33 and blood compatible, low‐adhesion coatings 34. These materials may be used in the flexible as‐formed condition or heat treated to remove organic components and induce porosity35 or increase mechanical rigidity 36. The use of metal oxide additions to polymers has been recognized in the development of bioadhesive properties for drug delivery37 and is promising for modulating the adhesion of cells to PDMS.…”

Metal-organic chemistry allows for molecular mixing and creation of a range of submicron phase-separated structures from normally brittle metal oxides and flexible polymers with improved bioactivity and delivery properties. In this study, we used a high throughput platform to investigate the influence of organic metal oxide doping of polydimethylsiloxane (PDMS) coatings on cellular bioactivity and controlled release of vanadium compared with titanium oxide coatings without additional PDMS. Metal-organic-derived titanium and or vanadium was doped into PDMS and used to form a coating on the bottom of cell culture microplates in the absence of added water, acids, or bases. These hybrid coatings were rapidly screened to establish how titanium and vanadium concentration influences cell proliferation, adhesion, and morphology. We demonstrate that titanium doping of PDMS can be used to improve cell proliferation and adhesion, and that vanadium doping caused a biphasic dose response in proliferation. A 28-day vanadium and titanium elution study indicated that titanium was not released, but the presence of PDMS in coatings increased delivery rates of vanadium compared with titania coatings without polymer. Hybrid coatings of titanium-doped polymers have potential for improving wound healing dynamics, soft-tissue integration of medical implants, and use as controlled delivery vehicles.

“…Although these materials decompose readily between 300 o C-400 o C [15], under high vacuum environments, such as the one in the PLD chamber, the degradation of polymer structure can take place at even lower temperatures.…”

Erbium doped tellurite glass thin films were deposited using excimer (193 nm) laser ablation onto two different types of substrates: silica and polymer-coated silica for engineering optical integrated active-passive devices. The deposition conditions were optimized for both substrates in order to produce high quality rare-earth (Er 3+ ) ion doped glass thin films with low propagation loss. The optical and spectroscopic properties of the deposited films, namely transmittance, fluorescence, lifetime as well as refractive indices at 633 nm were measured and analyzed in detail.

“…These porous PDMS materials can be prepared using sugar, [18] salt, [19] self-assembled colloidal microspheres, [20] suspension polymerization, [21] emulsion droplets, [22][23][24] and CO 2 gas generated by NaHCO 3 as templates, [25] among which the sacrificial sugar template technique has been the most popular because of its simple steps, cost effectiveness, and ecofriendliness. [26,27] Recently, porous PDMS materials have been successfully synthesized for selective oil absorption from water. For example, Choi et al fabricated PDMS sponges with fast oil absorption and excellent recyclability using sugar particles as templates.…”

This study described an approach to impart controlled morphology and improved pore interconnectivity to poly(dimethylsiloxane) (PDMS) sponges for oil sorption by partially fusing the sugar particles together prior to creation of a continuous PDMS matrix. PDMS sponges with high absorption capacity, low water pickup, and remarkable reusability were fabricated by the polymerization of the PDMS prepolymer and a curing agent in cyclohexane. The PDMS sponge showed oil absorbency in the range from 790% to 4000% for various oils solvents, with the maximum absorption capacity reaching up to 23 times of its weight. Compressive modulus of PDMS subjected to sugar fusion for 24 hr was significantly increased to 1900 Mpa. The sponge also exhibited excellent repellency to corrosive strong acid and alkali. Besides, oil can be quickly adsorbed in tens of seconds and maintained for several months. Furthermore, PDMS sponges showed little loss of their absorption capacities and owned weights after 20 absorbing/recovering cycles. Copyright © 2015 John Wiley & Sons, Ltd.
