Properties of (meth)acrylate copolymer grafted with long fluorinated side chain prepared by “graft onto” strategy

Abstract

A (meth)acrylate copolymer grafted with long fluorinated side chains (AGLF) was synthesized successfully through a two‐step procedure. First, a carboxyl terminated fluoropolymer, poly(2,2,3,4,4,4‐hexafluorobutyl methacrylate) was synthesized by conventional radical polymerization in the presence of 3‐mercaptopropionic acid as chain transfer agent. And then the fluoropolymer was grafted to the in‐house synthesized polyacrylate (MMA‐r‐BA‐r‐GMA). Fourier transform infrared spectroscopy and 1H‐nuclear magnetic resonance spectroscopy were employed to verify the synthesis of AGLF. Moreover, the surface properties were investigated by contact angle measurement and X‐ray photoelectron spectroscopy. The results proved that a small amount of poly(2,2,3,4,4,4‐hexafluorobutyl methacrylate) addition can create a hydrophobic surface effectively. Furthermore, the X‐ray photoelectron spectroscopy results showed that it is the AGLF grafted with longer fluorinated side chain that have more fluorine atoms enriched on the surface and thus performed better hydrophobicity and lipophobicity. Testified by thermogravimetric analysis and differential scanning calorimetry, it was found that AGLF films have excellent thermal properties. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

Investigation of covalently grafted polyacrylate chains onto graphene oxide for epoxy composites with reinforced mechanical performance

“…Besides, the characteristic absorption at 1641 cm −1 increase owing to the presence of CC group of the A‐174 silane coupling agents which indicate that A‐174 has been grafted to the basal plane of GO sheets successfully. The incorporation of PA chains onto the surface of A‐GO sheets is confirmed by the much weaker absorption band at 1637 cm −1 (stretching vibration of CC bonds) compared to A‐GO spectrum which indicates that the CC bonds of A‐GO have participated in the polymerization, and the band at 910 cm −1 corresponding to the characteristic peak of epoxy group in PA chains, and the absorptions at 2954 and 1378 cm −1 due to stretching vibration of CH 2 and CH 3 groups, and the peaks at 1740 and 1267 cm −1 owing to the characteristic absorption of ester bond . Furthermore, 1 H NMR analysis is employed to further characterize the structure of PA‐GO in CDCl 3 solution (Figure ).…”

“…are also reported. [22][23][24][25][26][27][28] Depending on the chemical structure of reagents, more hydrophobic or more hydrophilic type graft copolymers than initial polymeric materials can be prepared. According to the literature survey, polymerization techniques such as anionic, cationic, free-radical polymerizations, ringopening metathesis polymerization, atom transfer radical polymerization or other such as ring-opening olefin metathesis polymerization, radiation or iniferter induced polymerizations and polycondensation reactions are commonly used to the preparation of the modified materials.…”
