Researchers have developed a new way to use plant oils like olive and linseed oil to create polyurethane, a plastic material used in everything from foam insulation panels to tires, hoses and sealants.
The researchers, led by Michael Kessler, Berry Family director and professor in Washington State University’s School of Mechanical and Materials Engineering, have published a paper (http://pubs.acs.org/doi/pdf/10.1021/am5071333) on the work in the journal ACS Applied Materials & Interfaces (http://pubs.acs.org/journal/aamick).
Polyurethane is extremely tough and corrosion- and wear-resistant, but researchers would like a more environmentally friendly alternative to the petroleum-based product. About 14 million tons of polyurethane was produced in 2010, and production is expected to increase by almost 30 percent by 2016.
While there are already some polyurethanes made from plant materials, Kessler’s research group developed a new method that uses vegetable oils to create materials with a wide variety of flexibility, stiffness and shapes. Plant oils are inexpensive, readily available, renewable and can be genetically engineered.
In the study, the researchers made polyurethane using olive, canola, grape seed, linseed and castor oils. While other researchers have struggled with using petroleum-based solvents, the WSU researchers, working with colleagues from Iowa State and from Cairo universities, didn’t use solvents or a catalyst in their production.
To make polyurethane, manufacturers combine two types of chemical compounds in a reaction. One of the chemicals is a polyol, which is a compound with multiple hydroxyl functional groups that are available for reaction.
Some oils, like linseed oil, have five or six reactive sites, making the material stiffer. Others, such as olive oil, have fewer reactive sites, making the material more flexible.
“What’s new about this is specifically the way we make the polyols,” said Kessler, who compared the process to building with Legos. “It is the same concept with these chemical groups. They click together and form a chemical bond.
“The novelty of this particular work is that these polyurethanes are using a new chemistry made by a combination of castor oil fatty acid and modified vegetable oils,” he said.
