Preparing fluorinated oligomers with tertiary amine structure for UV curable coatings

Tuesday, 11 October 2016

A novel fluorinated oligomer with tertiary amine structure was synthesised by isophorone diisocyanate, 2-hydroxyethyl acrylate, and fluorinated diol, which was prepared via Michael addition reaction between diethanolamine and dodecafluoroheptyl acrylate.

The structure of fluorinated oligomer was confirmed by FTIR. The prepared fluorinated oligomer was added into the UV curable coatings, the influences of fluorinated oligomer on the cured degree and double bond conversion was analysed by FTIR and gel content.

Cured films develop improved mechanical properties

The conversion ratio is increased when the fluorinated oligomer increased, which is due to the tertiary amine structure in the prepared product. The characteristics of UV cured films such as thermal properties, hydrophobicity, chemical resistance, mechanical properties, and hardness were characterised with TGA, contact angle, and DMA. Results show that thermal stability, hydrophobicity, and chemical resistance are improved when fluorinated oligomer is introduced into the UV curable coatings. The DMA and hardness results indicated that the mechanical properties of UV cured films were improved and the flexibility decreased.

The study is published in: Applied Polymer Science, Volume 134, Issue 2, January 10, 2017
