Abstract:
An apparatus and method related to a drug eluting stent with improved adhesion between a drug excipient coating and a stent substrate is described. In one embodiment of the present invention, an apparatus comprises a stent substrate formed of a metal and/or a polymer and having a surface modified by exposure to ultraviolet light and an atomic oxygen molecule. A polymeric material is coupled with the surface of the stent substrate. In another embodiment, a method includes providing a stent with an adhesive property that is associated with the surface of the stent. The adhesive property of the stent is modified by exposing the surface to ultraviolet light and an atomic oxygen molecule.
Abstract:
A process using ultraviolet light having a wavelength of 160 to 500 nanometers without higher wavelengths and a high intensity between about 1 and 40 watts/cm2 to surface treat a carbon containing fiber is described. The treated fiber contains an enhanced amount of oxygen on the surface which significantly improves the bondability of the fiber in composites.

A system and method for depositing a coating may comprise a coating chemical reactor, surface activation component, and a deposition component. A target surface may be prepared for deposition with the surface activation component. The coating chemical reactor may comprise a coating chemical dispenser and a coating chemical verifier that prepares the coating chemical for deposition. The coating chemical verifier may utilize an optical excitation source and at least one optical detector, wherein chemical substances are identified by unique signatures composed of binary code. The coating chemical may be received by the deposition component to depositing the coating chemical on the target surface.
Abstract:
A method using irradiation with optical light in the presence of a chemical dissolved in a solvent, which chemical reacts with the surface in the presence of the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 308, 410, 508) as the solvent containing the dissolved chemical on the surface. The treated surfaces are more paintable and bondable.
Abstract:
Process for the treatment of shoe soles through ultraviolet radiation combined with ozone. The treatment is applicable to the surface of sole materials which are used in the shoe making industry in order to improve their adhesion properties with various adhesives. The treatment comprises applying low wave length ultraviolet radiation to the sole material by means of an apparatus having a chamber which contains ozone; introducing the sole inside the chamber; controlled removal of ozone, and a system for expelling the treated sole from the chamber.

Abstract:
A pretreatment method for application of coating to shoe parts is capable of replacing the conventional primer coating process with the UV radiation process. The coating pretreatment to the shoe parts can be carried out continuously in an automatic manner. Besides, creating etching effect by using UV-C radiation and ozone activating improves the bonding of the shoe parts to the adhesives, without substantial increase in equipment cost. A pretreatment system for application of coating to shoe parts can be provided with more reaction chambers for UV-C radiation and cleaning, so as to increase the breadth of application of the UV radiation system. Subjecting the surface of the shoe parts to UV-C radiation and cleaning process more than one time can activate the surface, and improve the follow-up coating quality.
Abstract:
A film-forming line is for forming a film on a substrate, and includes a surface-improving treatment device, a film-forming solution applicator, and a timer controller. The surface-improving treatment device is configured to perform a surface-improving treatment on the substrate. The film-forming solution applicator is configured to apply to the substrate a film-forming solution, which is for forming the film, after the substrate has been subjected to the surface-improving treatment by the surface-improving treatment device. The time controller is configured to obtain a time period since the time the surface-improving treatment is conducted by the surface-improving treatment device on the substrate. The present invention allows a film with a substantially uniform thickness to be formed on a substrate.
Abstract:
A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelengths with cooling of the surface during the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light is filtered or the lamp (24, 106, 212, 306, 510) is restricted to the limited range to avoid the affects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 306, 410, 508) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.
