Area of Science:

• Polymer Chemistry
• Environmental Science
• Materials Science

Background:

• Traditional water remediation materials often rely on metal-based or linear polymer structures.
• Developing sustainable and efficient materials for removing pollutants like dyes and heavy metals is crucial.

Purpose of the Study:

• To synthesize a novel biodegradable superstructured cross-linked polyamide-ester material.
• To evaluate the material's efficacy as a water remediator for dyes and mercuric ions.
• To investigate the sensing capabilities of the functionalized polymer for heavy metals.

Main Methods:

• Thiol-alkene photoclick chemistry was employed for material synthesis.
• Adsorption kinetics were studied to quantify dye removal efficiency.
• Density Functional Theory (DFT) calculations were performed to understand mercury complexation.

Main Results:

• The synthesized polyamide-ester material demonstrated thermal stability and biodegradability.
• The material efficiently adsorbed over 95% of rhodamine B and methylene blue dyes within 24 hours.
• The rhodamine B-functionalized polymer successfully sensed mercuric ions, forming a stable complex as confirmed by DFT.

Conclusions:

• The developed biodegradable polymer is a promising candidate for water remediation applications.
• The material's ability to adsorb dyes and detect heavy metals highlights its versatility.
• The study presents a novel approach to creating functional materials for environmental monitoring and cleanup.
