Protocol

This report details a microwave-initiated approach for deposition of porphyrin functionalized porous organosilicate sorbents on a cotton fabric and demonstrates reduction in 2-chloroethyl ethyl sulfide (CEES) transport through the fabric resulting from this treatment.

Difficulty
intermediate
Total time
~4–6 hours (including microwave processing, dip coating, functionalization, and drying)

Steps

1
Initiate microwave-assisted material synthesis

Apply microwave heating to facilitate chemical reactions for sol preparation. This microwave initiation step accelerates the formation of porous organosilicate precursors.

2
Prepare sol solution for dip coating

Mix and prepare the porphyrin-functionalized porous organosilicate sol to achieve appropriate viscosity and composition for fabric coating application.

▶ 01:28
3
Dip coat fabric in prepared sol

Immerse cotton fabric in the prepared sol solution and remove excess coating to achieve uniform sorbent deposition on the fabric surface.

▶ 02:12
4
Functionalize coated fabric with porphyrin

Apply porphyrin functionalization chemistry to the sol-coated fabric to impart selective binding and sorption properties for chemical vapor capture.

▶ 02:52
5
Characterize sorbent-coated fabric properties

Analyze morphology, composition, and chemical vapor transport reduction (CEES) performance of the porphyrin-functionalized porous sorbent on fabric using appropriate analytical techniques.
