TL;DR: It is shown that prestraining the film further improves the performance of electrical actuators made from films of dielectric elastomers coated on both sides with compliant electrode material.
Abstract: Electrical actuators were made from films of dielectric elastomers (such as silicones) coated on both sides with compliant electrode material. When voltage was applied, the resulting electrostatic forces compressed the film in thickness and expanded it in area, producing strains up to 30 to 40%. It is now shown that prestraining the film further improves the performance of these devices. Actuated strains up to 117% were demonstrated with silicone elastomers, and up to 215% with acrylic elastomers using biaxially and uniaxially prestrained films. The strain, pressure, and response time of silicone exceeded those of natural muscle; specific energy densities greatly exceeded those of other field-actuated materials. Because the actuation mechanism is faster than in other high-strain electroactive polymers, this technology may be suitable for diverse applications.

TL;DR: In this article, a silicone nanofilament-coated textile is used as a membrane for oil/water separation and as a bag for selective oil absorption from water, which is a very promising material, e.g., for practical oil absorption.
Abstract: Superhydrophobic and superoleophilic polyester materials are successfully prepared by one-step growth of silicone nanofilaments onto the textile via chemical vapor deposition of trichloromethylsilane. The successful growth of silicone nanofilaments is confirmed with scanning electron microscopy, energy-dispersive X-ray analysis, and investigation of the wetting behavior of water on the textile. Even microfibers deeply imbedded inside a woven material could be coated very well with the nanofilaments. The coated textile is water repellant and could only be wetted by liquids of low surface tension. The applications of the coated textile as a membrane for oil/water separation and as a bag for selective oil absorption from water are studied in detail. Owing to the superwetting properties and flexibility of the coated textile, excellent reusability, oil/water separation efficiency, and selective oil absorption capacity are observed, which make it very promising material, e.g., for practical oil absorption.

TL;DR: In this paper, a method of coating implantable open lattice metallic stent prosthesis is disclosed which includes sequentially applying a plurality of relatively thin outer layers of a coating composition comprising a solvent mixture of uncured polymeric silicone material and crosslinker and finely divided biologically active species, possibly of controlled average particle size.
Abstract: A method of coating implantable open lattice metallic stent prosthesis is disclosed which includes sequentially applying a plurality of relatively thin outer layers of a coating composition comprising a solvent mixture of uncured polymeric silicone material and crosslinker and finely divided biologically active species, possibly of controlled average particle size, to form a coating on each stent surface. The coatings are cured in situ and the coated, cured prostheses are sterilized in a step that includes preferred pretreatment with argon gas plasma and exposure to gamma radiation electron beam, ethylene oxide, steam.

TL;DR: In this article, a design and method of manufacture for an electrosurgical electrode with a silicone coating is described, which resists the buildup of eschar and provides high tear strength and added durability.
Abstract: A design and method of manufacture is disclosed for an electrosurgical electrode with a silicone coating The coating resists the buildup of eschar The silicone material is thick enough in the flat area of the blade to withstand the electrosurgical voltage without breakdown The electrosurgical current path is primarily through the blade edges and tip The flat of the blade remains insulated under most conditions The relatively thick coating also provides high tear strength and added durability The composition of the electrode coatings may include silicone elastomers in the form of adhesives, dispersions, or liquid rubbers The coating composition may also contain adhesion promoters, heat stabilizers, plasticizers, release enhancers, crosslinking agents, and colorants Several methods of manufacture are illustrated by way of examples

TL;DR: The present study finds a "viscosity" that would maintain the "clarity" of the vitreous of rabbits and help in "replacing the retina" in plastic surgery and retinal detachment procedures.
Abstract: Introduction Silicone rubber has been widely used as implant material in plastic surgery and in retinal detachment procedures. 1 Liquid silicone was first injected into the vitreous cavity of rabbits by Stone, 2 who reported that silicone fluids of various viscosities were well tolerated and produced "very little change in the rabbit eyes over a period of two years." He went on to predict that it might be possible to find a "viscosity" that would maintain the "clarity" of the vitreous and help in "replacing the retina." Recently, other investigators 3-5 have confirmed Stone's observations. However, their animal experiments emphasized the possibilities of complications. Everett 4 reported cataract formation following the injection of liquid silicone into the vitreous cavity of rabbits; Galavin 5 produced glaucoma by the injection of liquid silicone into the posterior chamber of the rabbit eye. The present study serves a dual purpose: (1) to report further
