  2. Solid surface material - Wikipedia

    en.wikipedia.org/wiki/Solid_surface_material

    Solid surface material, also known as solid surface composite, [1] is a man-made material usually composed of a combination of alumina trihydrate (ATH), acrylic, epoxy or polyester resins and pigments. It is most frequently used for seamless countertop installations. A solid surface material was first introduced by DuPont in 1967 under the name ...

  3. Spinning (polymers) - Wikipedia

    en.wikipedia.org/wiki/Spinning_(polymers)

    The direct spinning process avoids the stage of solid polymer pellets. The polymer melt is produced from the raw materials, and then from the polymer finisher directly pumped to the spinning mill. Direct spinning is mainly applied during production of polyester fibers and filaments and is dedicated to high production capacity (>100 ton/day).

  4. Solid-state electrolyte - Wikipedia

    en.wikipedia.org/wiki/Solid-state_electrolyte

    All-solid-state electrolytes are furthermore divided into inorganic solid electrolyte (ISE), solid polymer electrolyte (SPE) and composite polymer electrolyte (CPE). On the other hand, a QSSE, also called gel polymer electrolyte (GPE), is a freestanding membrane that contains a certain amount of liquid component immobilized inside the solid matrix.

  5. Sol–gel process - Wikipedia

    en.wikipedia.org/wiki/Sol–gel_process

    Schematic representation of the different stages and routes of the sol–gel technology. In this chemical procedure, a "sol" (a colloidal solution) is formed that then gradually evolves towards the formation of a gel-like diphasic system containing both a liquid phase and solid phase whose morphologies range from discrete particles to continuous polymer networks.

  6. Nafion - Wikipedia

    en.wikipedia.org/wiki/Nafion

    The combination of fluorinated backbone, sulfonic acid groups, and the stabilizing effect of the polymer matrix make Nafion a very strong acid, with pK a ~ -6. [8] In this respect Nafion resembles the trifluoromethanesulfonic acid , CF 3 SO 3 H, although Nafion is a weaker acid by at least three orders of magnitude.

  7. 3D microfabrication - Wikipedia

    en.wikipedia.org/wiki/3D_Microfabrication

    One factor that limit broad applicability of self-folding polymer films is the manufacturing cost. Actually, polymer can be deposited by spinning and dipping coating at ambient conditions, the fabrication of polymer self-folding films is substantially cheaper than fabrication of inorganic ones, which are produced by vacuum deposition.
