Since the 1990s, major strides have been made in the use of ionic liquids (cold atmospheric plasma and plasma activated water) as antifungal agents for wood preservation. An Electro-Static Activated Polymer (E-SAP) has been developed that uses nano-technology to generate ionic liquids from energy harvested from surrounding electromagnetic fields (cell towers, satellites, etc.).  E-SAP has been used for more than 35 years that structurally repairs damage done by woodpeckers to wood poles and prevents decay from continuing in the repaired wood pole sections.
