Process for Improved Barrier PLA Film

Executive Summary Consumers, companies, and governments are increasingly favoring compostable materials over fossil-based alternatives, as waste from traditional materials has escalated significantly in recent decades. However, a key challenge with compostable materials is their inferior oxygen and moisture barrier properties compared to non-compostable...

Water Dispersible Poly(dimethylsiloxane) Coatings for PFAS Replacement

Executive Summary Polyethylene-, polyvinylidene chloride-, and per- and polyfluoroalkyl substances (PFAS) -coated paper is used in applications requiring barrier properties such as grease and water resistance. However, the use of these chemicals present environmental challenges and make the coated paper difficult to recycle or compost. Researchers...

Biodegradable Barrier Coating for Paper

Executive Summary Coated paper is used in a variety of packaging applications including fresh produce, cheeses, confectionary, frozen fish and fast food. To achieve sufficient barrier properties, the paper is often coated with petroleum based waxes or polyfluorinated substances (PFAS). However, these coatings are not environmentally attractive and...

Topologically Controlled Composite Materials with High Energy Absorption Capability

Executive Summary Composite materials are a well-established technology in applications requiring high-performance such as sports, aerospace, or defense. However, conventional fiber reinforced composites are prone to severe delamination, cracking, and fiber breakage upon projectile impact. This lack of toughness is a critical limitation on the possible...

Machining Lubricant Containing Exfoliated Graphite

Executive Summary Machining processes in high production environment usually adopt flood cooling with water-based lubricants and various chemicals. In order to minimize the lubricant use and waste (which also eliminate centralized pumping stations), minimum quantity lubrication (MQL) techniques have been adopted, which generate mist of oil droplets....

Process for Depolymerizing Recycled Polystyrenes

­Executive Summary Each year, billions of lbs of polystyrene and styrene copolymers are discarded as waste and very little is recycled. While some technologies have attempted pyrolysis in fluidized bed reactors or solvent processes to convert the polystyrene back to monomer, high costs, long process times and a myriad of reaction products have...

Rapid Process for Depolymerizing Recycled PET

­Executive Summary Each year, billions of lbs of polyethylene terephthalate (PET) and polyethylene terephthalate glycol (PETG) are discarded as waste. While some of the material is separated, recycled and incorporated into new materials, the degradation of the polymers back to their original monomers (a.k.a. chemical recycling) remains prohibitive...

100% Recyclable, Fluorine- and Plastic-Free Fat, Grease and Water Resistant Paper Coating

Executive SummaryWith a societal push to remove plastics from the food industry, there is a need for alternative packaging solutions. Governments and corporations alike have begun banning various single-use plastic products in favor of protecting the environment. This technology seeks to improve polymer coating materials for paper products. This technology...

System for Coating Inner Diameter Surface

Executive SummaryDiamond-like coatings offer a coating solution rivaled by few technologies available today. Capable of improving the durability and extending the lifetime of many metallic products, these coatings are typically applied in Physical Vapor Deposition (PVD) chambers. PVD processing is a line-of-sight process, meaning the distance between...
