A coating applicator tool head configured for use with a robotic maintenance device includes a tool head body with a frame, a supply container, a drive for actuating delivery of flow of coating from the supply container, a feed tube, a nozzle receiving flow from the feed tube, and a spreading tool such as a roller brush or a spatula receiving flow from the nozzle. The coating applicator tool head is moved by an articulated arm of the maintenance device over surface of a wind turbine blade containing damage such that the roller brush or spatula can apply layers of the coating to cover and fill in the damage. The nozzle directly supplies coating continuously onto the roller brush or the spatula, and the drive can be configured to independently adjust supply of two or more different components in the supply container that may be mixed to form the coating.

Disclosed is a glass-based flexible cover window with improved strength including a planar portion formed so as to correspond to a planar region of a flexible display and a folding portion formed so as to be connected to the planar portion, the folding portion being formed so as to correspond to a folding region of the flexible display, wherein the flexible cover window includes a glass substrate and a polyimide (PI) coating layer formed on the glass substrate. The PI coating layer is formed on the glass substrate by direct coating, whereby inherent texture of glass is maintained while the overall thickness of the flexible cover window is reduced, and therefore aesthetics of the flexible cover window are improved.

A method is provided to make a nano-silver paste. An organic acid is used as a protective agent. Silver nitrate is used as a source of silver ions to reduce silver nanoparticles on a surface protected by the organic acid. The particle size of the silver nanoparticle is 45 nanometers. In the other hand, a silver precursor of organic metal is synthesized. The organic metal is cracked at 200 celsius degrees (° C.) to fill pores left during sintering. After mixing the silver nanoparticle, the silver precursor and the solvent, the nano-silver paste is obtained. After being heated at 250° C. for 30 minutes, the nano-silver paste has a resistance of (3.09±0.61)×10.sup.−5 Ω.Math.cm. By being heated at 250° C. and applied with a pressure of 10 MPa to be hot-pressed for 30 minutes for joining copper to copper, the nano-silver paste obtains a bonding strength reaching 36 MPa.

The present teachings contemplate a method comprising coating a poly(vinyl chloride) material with a composition including a dicarbonyl compound, a cyanoacrylate compound, or a combination thereof and a viscosity modifying agent so that the composition has a viscosity of from about 50 cps to about 2500 cps; wherein the coated poly(vinyl chloride) material is capable of adhering to a second material without the use of a primer.
