Resumen

La humedad hace que las fibras de papel se expandan linealmente con el aumento de la humedad relativa. Esta expansión del papel ocurre en dos etapas, lo que indica sitios de adsorción de agua distintos dentro de la estructura del papel.

Sus antecedentes:

La humedad impacta significativamente las propiedades del papel, afectando aplicaciones como la impresión y el embalaje.
La absorción de agua en las fibras de papel conduce a la expansión (hidroexpansión o higroexpansión).

Conclusiones:

La expansión de las fibras de papel es directamente proporcional a la humedad relativa.
El modelo de Guggenheim-Anderson-de Boer describe con precisión la sorción de agua en el papel.
Mecanismos de adsorción de agua distintos influyen en los cambios dimensionales del papel.
La AFM proporciona información crítica sobre el comportamiento a nanoescala del papel bajo diferentes humedades.

Palabras clave:

Adhesion

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow...

Analyte Adsorption and Distribution

Analyte Adsorption and Distribution

In certain chromatographic separations, solutes transfer between the mobile phase and the stationary phase via sorption, which typically refers to the process of adsorption. For many chromatographic systems, the sorption process often depends on the polarity of the compounds—an expression of the overall dipole moment within the molecule. During the separation process, there is competition between the solute and solvent for adsorption to the stationary phase. Highly polar compounds and...
