ABSTRACT: The Air Force requires an advanced corrosion resistant coating system which significantly mitigates the destructive effect of oxygen, for military aerospace and infrastructure preservation applications. The proposed program will develop an advanced multifunctional hybrid corrosion resistant coating system by uniformly embedding self-healing nanoparticles into a superhydrophobic perfluoroalkylated phthalocyanine (PPC) based fluorinated polymer system. The proposed new corrosion resistant coating system is expected to exhibit extremely low energy surface, surface self-cleaning feature by photo-generated singlet oxygen, no electron loss by encapsulated metal regulation, minimal oxidative destruction due to less hydrocarbon bonding, self-healing functionality by incorporation of corrosion inhibitor loaded nanocontainers, long-term active corrosion resistance by robust coating component, and high film durability by incorporated temperature stable polymer. This advanced coating system will also provide improved insulation film formability and enhanced thermal stability and processability due to the proven polyurethane polymer system. The key innovation in this approach is the unique design and synthesis of superhydrophobic main anticorrosion coating resin, which is fluorinated polymer prepared by covalently bonding of PPC groups to the backbone of fluorinated polyurethane polymer, and the incorporation of self-healing mesoporous silica nanoparticles (MSNs). The proposed advanced corrosion resistant coating system can be economically scaled up for volume manufacture. BENEFIT: The proposed high performance multifunctional hybrid corrosion resistant coating system will provide significantly increased corrosion resistance property and the lifetime of military aircrafts, thereby significantly reducing corrosion related operation and maintenance costs. The proposed corrosion resistant coating system can be applied to other military helicopter and rotorcraft, aircraft carriers, warships, armored vehicles, other land vehicles, and engineered structures where similar performance is needed. Also, the ability to form superhydrophobic coatings surfaces will have a huge effect on commercial applications such as anti-corrosion, antifouling, commercial marine structures/vessels, and automotive, commercial aircraft and vehicles, civilian infrastructure, and other consumer applications.

Scintillators have been used in radiation detection applications including medical imaging, oil well drilling, and high energy physics experiments. The new security need for scintillators has changed the market dynamics from specialty niche to volume production. In this program, Nanotrons proposes a manufacturing method that potentially produces scintillator of very large size and high crystal quality at unprecedentedly low cost to meet the new demand. Our process is a novel simple process that grows large-size single crystal ingots by continuous solidification from a seed crystal without any moving parts. Due to the simplicity, the proposed process has salient advantages of large size and low cost. Without movements, the new process also prevents secondary nucleation and ensuring very low strain in the grown crystal. Phase I will demonstrate the feasibility.

In order to meet NASA's vision to develop sustainable and affordable solar system exploration strategies, NASA seeks advanced high-strength and high-toughness composite materials with the microcrack resistance at cryogenic temperatures. These materials must be suitable for use in fuel containment of liquid oxygen, hydrogen, and methane. The objective of this SBIR project is to develop advanced high microcrack-resistant composite cryotanks. In Phase I we successfully demonstrated the synthesis of functionalized graphene sheet (FGS) nanofillers in large scale, which exhibited significantly increased resin strength and toughness at both room and low temperatures, and reduced coefficient of thermal expansion (CTE). The further investigation of nanocomposite formulation and composite processing can result in FGS-polymer nanocomposite based carbon fiber reinforced polymer (CFRP) composites with significantly enhanced microcrack resistance at cryogenic temperatures in ways it has never done before. The new nanocomposite based CFRP composite materials also provide additional advantages in forming an impermeable barrier to gas and liquid molecules ideal for fuel tanks. Nanotrons' proposed new multifunctional nanocomposite based CFRP composite cryotanks will replace the currently used aluminum-lithium cryotanks providing significant weight savings and can be economically manufactured.

NASA seeks advanced high strength and toughness composite materials with the highest microcrack resistance at cryogenic temperatures suitable for use in fuel containment of liquid oxygen, hydrogen, and methane. Nanotrons Corporation, in collaboration with Prof. Bungki Kim at NSF nanomanufacturing research center in University of Massachusetts Lowell, proposes to develop lightweight functionalized graphene sheets-polymer nanocomposite materials for advanced composite cryotanks. By uniformly dispersing high performance functionalized graphene sheets through novel polymer matrix the new lightweight nanocomposite will be fabricated and should exhibit significantly increase resin strength and modulus and reduce coefficient of thermal expansion of polymer resin. The resultant nanocomposite material can much increase the resistance to microcracking at cryogenic temperature in ways it has never done before. The new composite materials also provide additional advantages in forming an impermeable barrier to gas and liquid molecules ideal for fuel tanks. Nanotrons' proposed new multifunctional nanocomposite based carbon fiber reinforced polymer composite cryotanks will replace the currently used aluminum-lithium cryotanks providing significant weight savings and can be economically scaled-up for manufacturing. Phase I will demonstrate the feasibility of our approach.

This Small Business Innovation Research Phase I project will develop a new category of high energy density nanocomposite dielectric materials for use in high pulse power capacitors. The approach is to bring together 3 nanostructures in a polypropylene matrix to form a novel nanocomposite material with high effective dielectric constant, high breakdown voltage, and low dissipation factor. These high-performance nanocomposite dielectric materials may be used in many commercial high-power pulse, fast pulse, and high-energy density capacitors, resulting in reduced size, reduced weight, and improved circuit design. The commercial opportunities include high density electronic devices and packaging for medical, communication, transportation, and power distribution systems, in products such as defibrillators, medical and commercial lasers, pulse forming networks, A.C. motors, ultrasonic transducer exciter, strobe lighting, and acceleration and energy recovery systems of automobiles.
