A light-activatable
polymer composition and
polymer composite includes a
polymer binder selected from
epoxy resins, silica filled
epoxy, bismaleimide resins, bismaleimide triazines, fluoropolymers, polyesters,
polyphenylene oxide / polyphenylene
ether resins,
polybutadiene / polyisoprene crosslinkable resins (and copolymers),
liquid crystal polymers, polyamides,
cyanate esters, or combinations thereof, the polymer binder being present in an amount from 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 96, or 97 weight-percent of the total weight of the
polymer composition; a
spinel crystal filler present in an amount from 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, 50, 55 and 60 weight-percent of the total weight of the
polymer composition, and methods for making same are provided.
