AI Article Synopsis
- Mechanophoric polymers change chemically when exposed to mechanical force, making them a special type of smart polymer.
- Researchers designed a new mechanophoric polymer using epoxy-functionalized rhodamine by modifying it with glycidyl methacrylate.
- This new crosslinked polymeric film shows unique mechanophoric properties when subjected to UV light and stretching.
Article Abstract
Mechanophoric polymers are an interesting class of smart polymers which contains a special force-sensitive molecular motif that can lead to a chemical change within the polymer network in response to mechanical force. This investigation reports the design of a mechanophoric polymer based on epoxy-functionalized rhodamine via a monomeric approach. In this case, rhodamine (Rh) is modified with glycidyl methacrylate (GMA) through an epoxy-amine reaction to design a vinyl-functionalized multi-armed macromonomer (Rh-GMA), which is reacted with butyl acrylate (BA) to prepare the crosslinked polymeric film. The crosslinked polymeric film demonstrates mechanophoric properties under UV and stretching conditions.
