The present disclosure relates to materials, and specifically to materials such as sheet, molded or extruded polymer materials containing flake, formed, powdered, granulated or splintered borosilicate glass for heat rejection or mitigation and enhanced durability and strength. The invention provides a synthetic substrate that includes: 1 to 70 wt % borosilicate glass having an average size of 0.1 to 50 um; and 30 to 99 wt % polymer material, wherein the synthetic substrate has either a denier ranging between 0.1 to 20.0 or a thickness ranging between 0.1 to 20 MIL, which provides thermal management properties including reduction in solar absorptance and net power absorbed by surfaces. The greater the intensity of the solar radiation the more reactive the borosilicate becomes, reflecting and dissipating an increased level of energy.

A process for obtaining a material including a textured glass substrate coated, on at least one of its textured faces, with an antireflective coating of sol-gel type based on porous silica, includes a stage of application, to the at least one textured face of the substrate, of a solution containing at least one silica precursor and at least one pore-forming agent, then a heat treatment stage targeted at consolidating the antireflective coating. Before the application stage, the glass substrate is subjected to a preheating stage, so that the at least one textured face intended to be coated with the antireflective coating has a temperature within a range extending from 30° C. to 100° C. immediately before the application stage.

Mechanical strength of a composite material is enhanced by a simple process. In a composite material comprising a resin or a rubber and an oxide glass, the resin or the rubber is dispersed in the oxide glass, or the oxide glass is dispersed in the resin or the rubber. The composite material has a function that the oxide glass is softened and fluidized by electromagnetic waves.
