Nanocellular Foaming of Ultra High Molecular Weight Polyethylene using Ultrasound

Introduction Ultra high molecular weight polyethylene (UHMWPE) is a thermoplastic consisting of molecules of incredibly long chains with molecular weights of several million. It has the highest impact strength of any thermoplastic, has a high resistance to corrosion, moisture, and abrasion, and has a friction coefficient similar to that of Teflon. The ability to create nano-structured UHMWPE materials could yield many useful and unique properties, including mechanical and optical properties, and could dramatically increase the range of use for UHMWPE. Technology Description Professor Kumar at the University of Washington has developed a process that can create closed, nanoscale pores in ultra high molecular weight polyethylene (UHMWPE) using ultrasound. The process is rapid and inexpensive and has the potential to surpass the thin film limitations of the sol-gel process. Business Opportunity The ability to create nano-structured materials using ultra high molecular weight polyethylene (UHMWPE) both quickly and cheaply presents opportunities for incredibly resilient and lightweight structures. The material would be well suited for structural usage and in high-stress or high-impact environments. Applications are being sought in aeronautical and automotive fields. Other areas of potential application include commercial electronics and other consumer goods. Stage of Development A working methodology has been developed and characterized.
