Abstract
The effect of bemitil on the wettability and surface energy of a suspension of carboxymethylcellulose with aluminum powder during the formation of porous films
Incoming article date: 22.04.2025The effect of nanosized boehmite microadditives on the surface properties of carboxymethyl cellulose polymer suspensions with aluminum microparticles was studied. It was found that with an increase in the boehmite content from 0.10 g to 0.20 g in suspensions, the surface tension of liquid systems increases by 8 mN/m. The contact angle of the liquid composition wetting the fluoroplastic surface also increases: from 62 ° to 85 °. It is shown that on a low-energy fluoroplastic surface, boehmite nanoparticles act as a pore-forming agent, leading to the generation of ordered cells on the surface of films formed from suspensions. The morphology of the initial powders and the formed films with cells was studied using optical and electron microscopy. It was established that ordered cells of similar size with dimensions of ratio 500 to 1,000 microns in size are formed with a boehmite content in the base composition of 0.15 g.
