Welcome to Macromolecular Science and Engineering

Macromolecular science is the study of the synthesis, structure, processing, properties and use of polymers. These giant molecules are the basis of synthetic materials including plastics, fibers, rubber, films, paints, membranes, and adhesives.

Founded in 1963 as the first department for education and research in polymers in the nation, and recognized around the world as one of the best polymer programs in existence, the  Department of Macromolecular Science and Engineering at Case Western Reserve University is a world leader in all areas of polymer science and engineering.  As the first accredited undergraduate program in the United States in this field, the department continues to provide cutting-edge education in this exciting field.

We look forward to meeting you in person to discuss how we can assist you achieve your goals and dreams in your engineering education.

Recent News

First and #1: CWRU Macromolecular Science and Engineering ranked #1

The Department of Macromolecular Science and Engineering at Case Western Reserve University has been ranked as the #1 polymers/plastic engineering program in the United States. The department also has the distinction of being the first such department in the United States, having been founded in 1963.

Professor Liming Dai discusses smart windows on Science News

Professor Dai was recently featured on the Science/AAAS News website discussing recent research that demonstrates "smart glass" which can harvest energy from wind or precipitation to cause changes in transparency or color. This technology could be used in the future for more eco-friendly, responsive windows in structures.

Liming Dai: Integrating nanochemistry into the macroscopic world

Liming Dai is a professor in the department of macromolecular science and engineering at Case Western Reserve University (CWRU), US. He is also director of the Center of Advanced Science and Engineering for Carbon (Case4Carbon). Dai’s expertise lies across the synthesis, chemical modification and device fabrication of conjugated polymers and carbon nanomaterials for energy-related and biomedical applications.

Case Western Receives $540,000 Grant for Nanostructure Research

CLEVELAND, Ohio-- Researchers at Case Western Reserve University have received a $540,000 federal grant to work on ways of building nanostructures, tiny objects that can precisely deliver medicines to tumors, carry dyes that may help detect diseases, or serve as wires in electronics or computers.

"SPEAR, the Macro Graduate Student - Led Sustainability Initiative"

Sustainability in Polymers Education and Research is a group dedicated to teaching educators and students alike the importance of sustainability in polymers. This website is a portal linking teachers to educational tools such as outreach activities and presentations highlighting specific areas in the field of sustainable polymers.


Case Western Reserve University’s Eric Baer, PhD, and his colleagues have created an artificial lens that mimics a healthy 5-yearold’s eye.

The Gradient Refractive Index lens, or GRIN lens, gradually bends light as it passes through layers of two kinds of polymers, each just nanometers thick. Every one of the polymers has a different refractive index, which means light travels through them at different speeds.

Unlike eyeglasses, the lens can maintain focus across its surface—in practice, to the corners of the eye—and also can focus near and far.

In principle, squid should be a flop

In principle, squid should be a flop.

With no bones, the sea creatures' bodies are soft and squishy. But their beaks – yes, squid have beaks – are rock-hard and knife-edged, like an eagle's, the better to rip apart their prey. A squid's beak, made of one of nature's toughest materials, easily slices through a fish's spine.

Professors' "Ken" Ishida and Zehra Meral Ozsoyoglu receive university Distinguished Research Awards

Two Case School of Engineering faculty members are among the first professors to receive the university's newest recognition of faculty achievement: the Distinguished Research Awards. 
Hatsuo "Ken" Ishida, professor of macromolecular science and engineering, and Zehra Meral Ozsoyoglu, the Andrew R. Jennings Professor of Computing, were presented Distinguished Research Awards this spring by President Barbara R. Snyder and Provost W.A. "Bud" Baeslack III.

Case researchers developing self-healing polymers

CINCINNATI — Researchers at Case Western Reserve University have developed materials that can heal themselves.

A team, led by Case Western professor Stuart Rowan, is working on structurally dynamic polymers that respond to stimuli like ultraviolet light.

Rowan also is director of the university's Institute for Advanced Materials.
