Methods of producing an optical surface atop an exterior of a substrate that includes smoothing the exterior using an ALD process to sequentially deposit ALD layers to produce one or more ALD films that fill spaces between spaced-apart asperities existing on the exterior, and thereafter depositing a reflective material on the smoothed exterior of the substrate to produce the optical surface. The smoothing resulting from depositing the ALD film on the exterior of the substrate causes the grain size of the reflective material to be reduced in comparison to the grain size that would exists without having deposited the ALD film on the exterior of the substrate. The smoothing is sufficient to cause a reduction in grain size that results in a reduction in plasmon absorption in the optical surface in comparison to the plasmon absorption that would otherwise exist without having reduced the grain size of the reflective material.

Smoothing surface roughness using atomic layer deposition

The invention relates to the use of dicyanamide-containing ionic liquids which decrease the cure temperature of cyanate esters to form unique thermoset polymers having a triazine network. These thermoset polymers having the triazine network have an ionic character allowing for use in varied applications. The thermoset polymers described herein are useful in high temperature performance composites, and their high Tg makes them useful as a substitute for epoxies in the microelectronics industry. The thermoset polymers have good fracture toughness, excellent substrate adhesion, low shrinkage, and low moisture uptake.
