Limitations
The availability and cost of specific CAN materials might be a practical limitation for some design projects. Researching commercial availability is key.
Reliability & validity
The validity of this review relies on the comprehensive inclusion and accurate interpretation of existing peer-reviewed literature. Reliability is enhanced by the broad scope of studies covered.
Think critically
How might the 'on-demand' flowability of CANs introduce new design challenges related to long-term structural integrity under constant load or in extreme environments?
Design Principles
"Design for Circularity: Utilize materials with inherent properties that facilitate repair, reshaping, and recycling to minimize waste and extend product lifespan."
This breakthrough in material science addresses a significant limitation of traditional thermosets, which are notoriously difficult to recycle or reprocess once cured. By introducing dynamic covalent bonds, CANs allow for controlled bond exchange, facilitating reshaping and repair, thereby extending product lifespan and reducing waste.
What This Means for Your Design
Imagine a super-strong plastic that, when you heat it up, becomes soft enough to mold into a new shape or fix if it breaks. That's what Covalent Adaptable Networks (CANs) are all about – making strong materials that can be reused and repaired.
How to use in your project
- 1.Reference the properties of CANs when justifying material choices in your design project, particularly if you are aiming for recyclability or repairability.
- 2.Discuss how the development of CANs represents an advancement in materials science that designers can leverage for more sustainable solutions.

Paragraph starter
Covalent Adaptable Networks (CANs) represent a significant advancement in polymer science, offering a compelling alternative to traditional thermosetting polymers. Unlike conventional thermosets, which are permanently cross-linked and thus difficult to recycle or reprocess, CANs possess dynamic covalent bonds that allow them to be reshaped, repaired, and recycled upon heating. This unique characteristic enables the development of high-performance, lightweight products with extended lifespans and improved sustainability, addressing critical end-of-life challenges associated with conventional materials.
