[Analysis Case] Quantification of Hydroxyl Groups by Chemical Modification XPS

Evaluation of Hydroxyl Groups in Polymer Films

In controlling properties such as adhesion and wettability of polymer films, it is very important to quantitatively evaluate the polar functional groups (alcohol groups) present on the surface. XPS is optimal for quantitative evaluation; however, it is difficult to separate and quantify the adjacent oxidation state (C-O-C) and hydroxyl state (C-OH). In MST, after selectively reacting only the alcohol groups using a chemical modification method on polyvinyl alcohol (PVA), it is possible to quantify them using XPS. We present a case where the alcohol groups in PVA were chemically modified and evaluated using trifluoroacetic anhydride (TFAA). Measurement method: XPS, chemical modification Product fields: Electronic components, daily necessities Analysis purpose: Composition evaluation, identification, chemical bonding state evaluation For more details, please download the materials or contact us.
