Donald K. Grubbs is a notable inventor based in Rector, Pennsylvania, with a significant contribution to the field of materials science. He holds a total of eight patents, showcasing his innovative approach to developing advanced filler materials.

Latest Patents

Grubbs' latest patents include a filler material containing an anion substituted hydrotalcite. This invention focuses on an anion intercalated hydrotalcite filler material for polymer and paper systems. The filler material is formed through a method that involves reacting activated magnesia with an aqueous solution of aluminate and anions such as bromide, chloride, sulfate, and borate. This method can be executed at atmospheric pressure, resulting in high purity and yield of hydrotalcite. In a preferred embodiment, the aluminate solution is derived from sodium aluminate, sodium bromide, and sodium hydroxide, ensuring that the aqueous solution is substantially carbonate-free. Additionally, Grubbs has developed a method for the direct synthesis of anion substituted hydrotalcite, which eliminates the need for prior formation and activation of hydrotalcite before substituting anions.
