The US Army’s Hyperbranched Polymers spontaneously segregate to deliver active materials to the surface of a coating (A) compared to homogeneous distribution in a bulk system (B).

The US Army’s Hyperbranched Polymers spontaneously segregate to deliver active materials to the surface of a coating (A) compared to homogeneous distribution in a bulk system (B).

The US Army Research Laboratory (ARL) has demonstrated and patented a platform for spontaneously-segregating additives that migrate to the surface of a coating. This segregation reduces the total quantity of additive required to achieve high concentration at the surface and minimizes the impact of the additive on the bulk properties of the coating.

Hyperbranched polymers (HBP) are modified with fluorinated/aliphatic chains that buoy the molecule to the surface of a coating.  The HBPs can also incorporate a variety of anchors for adhesion in the coating and are engineered to deliver particular ionic species, bio-reactive sites, or catalysts to the coating surface without leaching.  Efficacy has been demonstrated in polyurethane, polyurea, and epoxy systems.  Validated concepts include waterproofing and antimicrobial applications.  Transport of additives to the surface has been increased 10-30x or more over bulk additives.  The technique was proven compatible with existing coating system and MilSpecs.
