The present invention relates to an inorganic paint composition, and a method for forming an inorganic paint film by using the same. The inorganic paint composition comprises: at least one alkali metal silicates represented by the following chemical formulas 1-3; phosphoric acid (H.sub.3PO.sub.4); one or more strong bases selected from KOH, NaOH and LiOH; and water (H.sub.2O) (In chemical formulas 1-3, x and y are 0.01-500, and n is a natural number of 1-20). [Chemical formula 1] xNa.sub.2O.ySiO.sub.2.nH.sub.2O, [Chemical formula 2] xK.sub.2O.ySiO.sub.2.nH.sub.2O, and [Chemical formula 3] xLi.sub.2O.ySiO.sub.2.nH.sub.2O. An inorganic coating film formed using the inorganic paint composition of the present invention has a strong binding force, regardless of the kinds of base materials, and thus shows excellent adhesion, adherence and the like to the base material and is not separated from the base material even after a long time.

A medical device for insertion or implantation in a body includes a polymer substrate and a layer of poly(vinyl pyrrolidone-alt-maleic anhydride) formed on a surface of the polymer substrate. Polymer chains of the poly(vinyl pyrrolidone-alt-maleic anhydride) are entangled with the polymer substrate.

Apparatus, materials, and techniques and techniques herein can include providing a deposited layer comprising a composite material including carbon nanotubes (CNTs). According to various examples, the composite can be applied to a substrate such as using a solution containing CNTs and other constituents such as sulfur. The solution can be spray-applied to a substrate, or spin-coated upon a substrate, such as to provide a uniform, conductive, and optically-transparent film layer. In one application, such a film layer can be clad or otherwise assembled in a stack-up including a substrate and cover layer (e.g., glass layers), such as to provide a transparent assembly. Such an assembly can include a portion of a window, such as a windscreen for a vehicle, where the CNT material can provide a conduction medium for Joule heating.

A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.
