These intrinsically water-repellent silicone thermoset polymers undergo covalent cross-linking to the fabric surface during curing, forming a rigid network of polymer chains that potentially stabilizes NP additives onto the woven cotton substrates; the microporous matrix seemingly stabilizing high particle ...
the interface, which through the use of the EDC molecule, a zero-length cross-linker, allowed covalent binding between terminal carboxyl groups on the SAM layer and primary amines on the bioreceptor with a good orientation, increas- ing likelihood of receptor-target recognition. To improve the ...
It is hydrophobic (reject water) and non-polar. Its bonds are covalent rather than ionic in character. It has a crystalline polymer structure. In Nafion™ tubing, interspersed throughout this Teflon matrix are sulfonic acid groups. These are hydrophilic (are drawn to water), polar, and ...
