Rong-Min Wang and his colleagues from Northwest Normal University in China, used emulsion polymerisation to synthesize a novel crosslinked core–shell emulsion of waterborne polyurethane-acrylic copolymers (PUA).

The average particle size of the PUA particle was approximately 130 nm. The researchers proved its core–shell morphology with transmission electron microscopy (TEM) and dynamic light scattering (DLS). FT-IR and TG confirmed its structure, too.

The humidity controlling coating (PUA-C) consists of pigments and porous fillers and the PUA.

Effects of humidity controlling

The researchers investigated the structure and properties of humidity controlling coatings with particular attention to the effects of the humidity controlling.

They observed the surface morphology of the PUA-C by scanning electron microscope (SEM).

Good results on humidity sensitivity

The humidity controlling coatings showed excellent properties of humidity sensitivity and humidity retention.

This investigation was published in Progress in Organic Coatings - online on 24 January 2013.
