Self-healing coatings and parts are next frontier for smart materials

Recent advances and ongoing improvements will help rapid and low-cost development of smart materials, and the next wave of innovation will be in self-healing coatings and parts, according to a new report.

Smart materials – those that change their properties in response to environmental stimuli, providing dynamic functionality – range from everyday items like photochromic lenses that darken in sunlight to complex ceramics and nanocomposites used in electronics.

Smart materials become faster to develop

Emerging classes of smart materials include self-healing materials, sensing materials, and shape memory materials, each of which has many potential applications.

“Today, researchers are beginning to develop software tools for predicting what structures will result in what smart properties. As a result, in the next five to ten years, these kinds of smart materials may become much faster and cheaper to develop,” said Anthony Vicari, Research Analyst and the lead author of a report titled “Get Smart: Smart Materials as a Design Paradigm”.

Focus is on self-healing materials

Analysts found that the focus is on self-healing materials. With applications in composites and coatings, self-healing materials are set to be the next frontier for smart materials. Such materials automatically repair damage to themselves through one of several chemical mechanisms.

The study also reports that varied companies hold patents. Over 300,000 patents have been granted across all smart material families even though few mention the term “smart material” in their titles, abstracts or claims. Patent filings peaked in 2012 at about 100,000, and top patent holders include heavyweights such as Siemens, IBM, GE and Samsung.

Commercialisation can occur rapidly

Researchers also reported that commercialisation can occur rapidly when conditions are right. Many classes of smart materials had long incubation times, but saw very rapid commercialisation once the time was right. Pieozelectric materials were long relegated to niche applications before booming due to adoption in mainstream products such as inkjet printers, digital cameras and smartphones.
