Epoxies are thermosetting polymers formed through the
combination of a resin and a hardener. They are extensively used for coatings,
for adhesives, and as a base for composite materials. Epoxies are recognized for
their versatility, high tensile strength, and high temperature resistance.
However, due to environmental and health concerns, there is a growing demand for
epoxies that are safer for both the user and environment.
Description
Michigan State University’s technology is the formulation of an eco-friendly
epoxy. This epoxy uses a biodegradable glucose-based copolymer, glucose maleic
acid ester vinyl copolymer (GMAEVC), in place of the typical synthetic
accelerators used in most epoxies. The resulting polymer matrix exhibits strong
mechanical performance and is effective for use as an eco-friendly
biocomposite.
Benefits
* Environmentally friendly composition: This formulation contains a biodegradable glucose-based copolymer
that acts as a hardener, eliminating the need for toxic curing agents.
* High
performance: The cured polymer matrix is
stable up to 300°C and maintains its mechanical performance in wet environments.
The cured polymer has a glass transition temperature as high as 100°C with a
storage modulus of 2500MPa.
* Demonstrated
applications as a biocomposite: The
polymer has good compatibility with hydrophilic natural fibers, making it an
ideal base for environmentally friendly biocomposites.
Applications
* Biocomposites
* Automotive
* Building materials
* A wide variety of other industrial
applications
