Composite advanced polymers for low moisture and oxygen permeability, Phase I

Completed Technology Project

Project Introduction

Composite advanced polymers for low moisture and oxygen permeability, Phase I
This Small Business Innovation Research Phase I program addresses NASA?s need for long duration shelf stable food by developing a high oxygen/moisture barrier polymer system with good optical quality and extended durability for food packaging. At the present time, processable polymers with good optical quality have only intermediate barrier properties, e.g., Nylon-6 and Polyester. Several groups have successfully reduced their moisture and oxygen transmission rates to 30% of their initial values by adding surface treated clays and/or oxygen scavengers, but the transmission rates are still too high. In this program, T/J Technologies will dramatically improve the barrier properties of transparent polymers by tailoring the processing and microstructure of nanocomposite systems. Specifically, we propose to achieve lower transmission rates using a combination of a high barrier polymer, a range of selected additives that can be oriented to reduce gas and vapor permeation, and solution based processing to improve additive dispersion and the ability to orient the additive. We anticipate the resulting materials will show >50% enhancement in oxygen and moisture barrier properties when compared to existing barrier polymer systems. More »
