Abstract
Described herein are modification of fabrics using a microwave initiation technique to produce a porous coating on the fibers providing adsorbent properties as well as the potential for further modification. In embodiments, the fabric incorporates a periodic mesoporous organosilica compound (PMO) optionally bound to a porphyrin or other functional group, and/or a catalyst or optical indicator.
Claims16
A method of treating fabric, the method comprising:
- wetting a fabric in a first solution comprising tetraethylorthosilicate (TEOS) to obtain a precursor fabric, and
- irradiating the precursor fabric with microwave radiation to obtain a TEOS functionalized fabric,
- wherein said organosilica precursor comprises:
- (1) bis(trimethoxysilyl)ethane (BTE) and 1,4-bis(trimethoxysilylethyl)benzene (DEB);
- or
- (2) mesitylene and BTE.
3 more elements
A modified fabric comprising:
- a fabric in a state of being modified by wetting the fabric in a first solution comprising tetraethylorthosilicate (TEOS) to obtain a precursor fabric, irradiating the precursor fabric with microwave radiation to obtain a TEOS functionalized fabric, dip-coating the TEOS functionalized fabric in a dip solution comprising surfactant and organosilica precursor to obtain dipped fabric, and curing the dipped fabric to obtain a modified fabric.
A modified fabric comprising:
- a fabric in a state of being modified by wetting the fabric in a first solution comprising tetraethylorthosilicate (TEOS) to obtain a precursor fabric, irradiating the precursor fabric with microwave radiation to obtain a TEOS functionalized fabric, wherein a functional group, catalyst, or optical indicator is chemically coupled to the fabric.
