Diacétate de cellulose Le diacétate de cellulose, appelé parfois simplement diacétate, est un polymère artificiel. En effet, il est fabriqué par traitement de la cellulose par l'acide acétique.
Il est constitué de deux radicaux acétate sur chaque unité de D-Anhydroglucopyranose de la molécule cellulosique.
Il est à différencier des acétate de cellulose et triacétate de cellulose.
Il est fragile parce qu'à base de cellulose. Lorsqu'il se détériore, la cellulose se rétracte et libère l'acide acétique, ce qui provoque un "syndrome du vinaigre".

| Résumé : |
Cellulose diacetate has been used in the cigarette filter industry due to numerous advantages such as its odorlessness, very good moisture absoption, non-toxicity and perfect filtering function. A systematic analysis on the surface of cellulose diacetate filament was made to compare the effect of different fiber fly quantity on cellulose diacetate filament. Scanning electron microscopy, Atomic Force Microscopy and X-ray Photoelectron Spectroscopy were used to characterize the morphology and elements on the surface of cellulose diacetate filament. In addition, specific surface area and surface hydrophilicity of cellulose diacetate filament were also tested. It was found that the quantity of exfoliated fiber fly had significant effect on the surface properties of filaments With the fiber fly quantity increasing, the contact angle of filaments decreased, and the O/C value increased, leading to the improvement of surface hydrophilicity. The gel particles dispersed in the filaments leaded to the protuberance formation on the filament surface. The surface roughness of filaments enhanced when the fiber fly quantity increased. The specific surface area test also showed that there was an increasing trend in the specific surface area of filaments with higher fiber fly content. |
