Mechanism of Hydration Induced Stiffening and Subsequent Plasticization of Polyamide Aerogel

The word "longitudinal" is corrected to "transverse" in two instances in the main text, as follows.1) In the "Results and Discussion / NMR Relaxometry" section: ORIGINAL SENTENCE: The longitudinal (spin-spin) relaxation times (T 2 ) of water protons can be distinct depending on the chemical environment of the corresponding water molecules.CORRECTED SENTENCE: The transverse (spin-spin) relaxation times (T 2 ) of water protons can be distinct depending on the chemical environment of the corresponding water molecules. 2) In the caption ofFigure 7: ORIGINAL SENTENCE: Both panels show the values of the longitudinal relaxation times (T 2 ) as the function of the water content of PAA.CORRECTED SENTENCE: Both panels show the values of the transverse relaxation times (T 2 ) as the function of the water content of PAA.This error has no further ramifications on the results or conclusions in the original manuscript.
