University of Virginia researchers solve a nearly 200-year-old challenge in polymers

Researchers at the University of Virginia School of Engineering and Applied Science have developed a new design that appears to rewrite the textbook on polymer engineering.

“We are addressing a fundamental challenge that has been thought to be impossible to solve since the invention of vulcanized rubber in 1839,” said Liheng Cai, an assistant professor of materials science and engineering, and chemical engineering.

That’s when Charles Goodyear accidentally discovered that heating natural rubber with sulfur created chemical crosslinks between the strand-like rubber molecules. This crosslinking process creates a polymer network, transforming the sticky rubber, which melts and flows in the heat, into a durable, elastic material.

Ever since, it’s been believed that if you want to make a polymer network material stiff, you have to sacrifice some stretchability.

India’s manufacturing slowed in November

India’s manufacturing growth slowed in November, marking its weakest level in 11 months due to price pressures and softer domestic demand. The HSBC India Manufacturing Purchasing Managers Index (PMI), compiled by S&P Global, recorded a reading of 56.5 for November, down from 57.5 in October and matching September’s level. Although the PMI remained above the 50-point threshold indicating expansion, it was below the preliminary flash estimate of 57.3, reflecting a more subdued rise in factory orders and production. Input costs rose at their fastest pace since July, driven by higher prices for chemicals, cotton, leather, and rubber.
