摘要:
A method and apparatus for bonding a first substrate to a second substrate can include an intermediate layer disposed between the substrates. In one embodiment, the intermediate layer can be disposed to a bonding area of the first substrate and only one adhesive layer can be disposed between the intermediate layer and the second substrate. In other embodiments, a plurality of intermediate layers can be used.

The present invention relates to colored reflective features, e.g., reflective security features or reflective decorative features, that optionally exhibit color shifting and to inks and processes for making such features. The features, as well as the inks optionally used to form the features, comprise nanoparticles and a colorant that preferably modifies a spectrum of light that is reflected by a reflective layer formed from the nanoparticles. The processes involve forming the features from one or more inks using a direct write printing process.

The invention relates to reflective features formed from multiple inks. In one embodiment, the reflective feature comprises a substrate having a first region and a second region, the first and second regions having different surface characteristics; a first reflective element disposed on the first region; and a second reflective element disposed on the second region, wherein the first reflective element is more adherent than the second reflective element to the first region. In another embodiment, the reflective feature comprises multiple layers formed from different inks exhibiting enhanced reflectivity and/or durability. The invention is also to processes for forming these features, preferably through a direct write printing process.

Anodized electroplated aluminum structures and methods for making the same are disclosed. Cosmetic structures according to embodiments of the invention are provided by electroplating a non-cosmetic structure with aluminum and then anodizing the electroplated aluminum. This produces cosmetic structures that may possess desired structural and cosmetic properties and that may be suitable for use as housing or support members of electronic devices.
摘要:
Described herein are methods of controlling metal nanowire morphologies by adjusting the reaction conditions of a polyol synthesis. In particular, by purging the reaction with an inert gas, batch-to-batch consistency can be achieved.
摘要:
This invention is directed to direct write printed reflective features comprising metallic particles and/or metallic nanoparticles. Preferably, the reflective feature are formed by a direct-writing printing process, e.g., a piezo-electric, thermal, drop-on-demand or continuous ink jet printing process, using an ink comprising metallic particles, e.g., metallic nanoparticles. The invention is also directed to inks suitable for printing such reflective features using a direct write printing process and to processes for making such reflective features.
摘要:
Composite particles comprising inorganic nanoparticles disposed on a substrate particle and processes for making and using same. A flowing aerosol is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains a liquid vehicle and at least one precursor. At least a portion of the liquid vehicle is removed from the droplets of precursor medium under conditions effective to convert the precursor to the nanoparticles on the substrate and form the composite particles.
