VACUUM INSULATED GLASS (VIG) UNIT INCLUDING NANO-COMPOSITE PILLARS, AND/OR METHODS OF MAKING THE SAME

摘要

Certain example embodiments of this invention relate to composite pillar arrangements for VIG units that include both harder and softer materials. The softer materials are located on the outside or extremities of the central, harder pillar material. In certain example embodiments, a high aspect ratio mineral lamellae is separated by an organic “glue” or polymer. When provided around a high strength pillar, the combination of the pillar and such a nano-composite structure may advantageously result in superior strength compared to a monolithic system, e.g., where significant wind loads, thermal stresses, and/or the like are encountered.

主权项

1. A vacuum insulated glass (VIG) unit, comprising:
first and second substantially parallel, spaced apart glass substrates defining a gap therebetween; an edge seal provided around a periphery of the first and second substrates to form an hermetic seal; a plurality of pillars provided between the first and second substrates; and a lamellar coating provided around at least a portion of the pillars so as to impart closure stresses on the first and/or second substrates proximate to the pillars to at least partially offset tensile stresses also applied to the first and/or second glass substrates, wherein the gap is provided at a pressure less than atmospheric.
