Sigma Aldrich Materials ScienceWe offer high-purity materials for micro- and nanoelectronics including electronic grade solvents, volatile precursors and CVD/ALD precursors, as well as products for nanopatterning and lithography. Conducting polymers, liquid electrolytes, catalysts, and anode/cathode materials are offered for fuel cells and batteries. Our extensive experience with inorganic materials and polymer products is applied to our line of biocompatible and biodegradable materials. Our comprehensive nanotechnology line includes nanoparticles, carbon nanotubes, indium tin oxide, dendrimers, and silsesquioxanes.
Sigma Aldrich’s vast range of materials can be divided up into the following categories:
· Biocompatible and Biodegradable Materials
· Display and Optoelectronics
· Energy Source Materials
· Micro and Nanoelectronics
· Nanomaterials
· Structural Materials and Electronic Ceramics
Biocompatible and Biodegradable MaterialsSignificant advances have been made in the development of biocompatible and biodegradable materials for biomedical applications, and in the case of the latter category, industrial applications, as well. Typically, inorganic and polymeric materials have been used for such items as artificial heart valves, synthetic blood vessels, artificial hips, medical adhesives, sutures, dental composites, and polymers for controlled slow drug delivery.
The parallel field of "biomimetics" strives to create materials for non-biological uses under inspiration from the natural world by combining them with manmade, non-biological devices or processes.
Display and OptoelectronicsThe world of display technology is changing with LCD, OLED and PLED devices leading the way. Aldrich is proud to offer an extensive selection of materials for this exciting field. Our products include a number of unique photoluminescent polymers and small molecules, charge transport materials, liquid crystals, triplet emitters, and other light-emitting compounds for LED synthesis applications. Aldrich also offers a significant number of dopant-functionalized materials, as well as ITO-coated glass and PET substrates.
Energy Source MaterialsSigma-Aldrich is proud to offer a broad range of products for advanced battery and fuel cell research including precious metal catalysts for electrolytes, conducting polymers, plasticizers and binders, acids, carbonates, and other liquid electrolytes. Our products include a number of solid polymeric electrolyte (SPE) materials such as Nafion®, as well as ceramic electrolytes for solid oxide fuel cells (SOFCs) like yttria-stabilized zirconia (YSZ). We also offer the highest purity electrochemical grade lithium salts and related compounds for advanced lithium ion batteries.
Micro and NanoelectronicsSigma-Aldrich provides a complete line of materials to serve the microelectronics and nanoelectronics markets. We offer a wide selection of high-purity metals, elements, gasses, metal halides, and superconductor and semiconductor powders. We have expanded our offerings of precursors for CVD/ALD thin-film semiconductor growth, metal deposition, and sol-gel processing. Our products can be custom packaged in bubblers and are available in research or bulk quantities.
NanomaterialsWe offer a variety of nanomaterials including polyhedral silsesquioxanes (PSS) (hybrid inorganic-organic nanoparticles) and silsesquioxane polymers, carbon nanotubes, fullerenes (buckyballs), as well as inorganic and metallic nanopowders, such as indium tin oxide, and nanoparticle dispersion. Dendrimers, sometimes referred to as starburst polymers, such as PAMAM, with varied cores, surfaces, and generations, show potential applications in such diverse fields as drug delivery or catalytic nanocomposites.
Structural Materials and Electronic CeramicsCeramics are nonmetallic, inorganic materials typically formed as powders and often sintered into useful forms. Semiconducting solids, solid oxide fuel cell electrodes, and thermally stable structural materials are all ceramics. Carbon materials from graphite, to diamond, to carbon nanotubes have many of the useful physical properties found in ceramics. Engineering polymers are materials with exceptional mechanical properties such as stiffness, toughness, and low creep which make them valuable in the manufacture of structural products like gears or electronic devices. Photooxidative stabilizers are often incorporated into structural polymers to help prevent
