- Description
- Image of CNT-parylene membrane fabrication TECHNOLOGY/BUSINESS OPPORTUNITY Second Skin: Ultrabreathable, Protective Membranes Opportunity : Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to license this innovative technology for collaborative research and development for commercialization. The technology consists of a novel composite membrane with tiny, nanometer wide pores that have the unique feature of transporting water vapor at exceptionally high rates. Incorporation of this material into garments can produce clothing that provide simultaneously high breathability and protection from small threats like viruses and bacteria. This property combination permits comfortable and safe operations to first responders, medical, civilian, and military personnel potentially exposed to contaminated environments. Other promising applications are in the membrane separation area, for ex. in pervaporation and membrane distillation processes. Background : In addition to protection from exposure to hazardous agents in the environment, a completely effective protective garment must also minimize physiological burden and prevent the risk of heat stress. The garment should allow facile perspiration and efficient heat loss from the body by evaporative cooling. Unfortunately, the techniques for protection and breathability (i.e., rapid water vapor transport) often work at cross purposes in a single material. Current protective materials sacrifice breathability in order to prevent exposure to harmful agents. They are typically either impermeable barriers that entirely block penetration of chemical and biological hazards (but also of water vapor), or heavy-weight laminates containing adsorbents for harmful agents. Macroporous membranes with high permeability to moisture vapor and air offer poor protection from hazardous materials. Because the ability of these materials to protect typically relies on hydrophobicity/oleophobicity, low-tension liquids can penetrate their porous network structure and potentially shuttle in other hazardous components. Furthermore, these macroporous materials are ineffective against vapor phase threats. Recent approaches to achieve adequate breathability in protective materials typically encompass selective monolithic membranes made of novel hydrophilic polymers, or multifunctional materials containing chemical groups/oxide nanoparticles with antibacterial or self-decontamination ability. Description : LLNL researchers have developed an alternative route to protective breathable membranes called Second Skin technology, which has transformative potential for protective garments. These membranes are expected to be particularly effective in mitigating physiological burden For additional information see article in Advanced Materials " Ultrabreathable and Protective Membranes with Sub-5 nm Carbon Nanotube Pores " Advantages : •· Membranes provide effective protection from biological threats by size exclusion rather than by merely preventing wetting. •· Material combines high breathability and protection in a single functional material. Potential Applications : Uses of LLNL's innovative CNT membranes include: Breathable membranes and fabrics Protective membranes Membrane distillation Pervaporation Water purification and desalination Development Status: LLNLresearchers have fabricated and tested cm2-area, flexible membranes. They have demonstrated that these membranes provide rates of water vapor transport that surpass those of commercial breathable fabrics, even though the pores are only a few nm wide and the overall porosity is less than 5.5%. LLNL has filed a patent application for this invention. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information. •· Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note: THIS IS NOT A PROCUREMENT. Companies interested in commercializing LLNL's Second Skin: Ultrabreathable and Protective Membranes technology should provide a written statement of interest, which includes the following: 1. Company Name and address. 2. The name, address, and telephone number of a point of contact. 3. A description of corporate expertise and facilities relevant to commercializing this technology. Written responses should be directed to: Lawrence Livermore National Laboratory Industrial Partnerships Office P.O. Box 808, L-795 Livermore, CA 94551-0808 Attention: FBO 346-17 Please provide your written statement within thirty (30) days from the date this announcement is published to ensure consideration of your interest in LLNL's Second Skin: Ultrabreathable and Protective Membranes technology.
