Surface polymerization of perfluorosilane treatments on paper mitigates HF production upon incineration†
Abstract
Hydrophobic paper has inspired advances in low-cost technologies. Of importance is the use of perfluorinated reagents, due to suspected release of HF. Surprisingly, by using a coupled TGA-IR-MS, we demonstrate that polymerization of a perfluorinated silane on paper, leads to rapid degradation, low-ash residue, and no toxic HF gas is produced under thermolysis.
