Introduction of Ionic Liquids as Highly Efficient
As a promising biodegradable polymer, cellulose triacetate (CTA) was synthesized and plasticized with ionic liquids to produce flexible biocomposite films multi-end-use. Initially, CTA polymer was synthesized from industrial waste cotton using a heterogeneous pathway. Subsequently, four ionic liquids, namely 3-hexyl-1-methyl imidazolium acetate [C6MIM][Ac], 3-hexyl-1-methyl imidazolium
Application of ionic liquids as low-volatility plasticizers
Plasticizers are used to improve flexibility, reduce cost and improve the processability of polymers. Ideally, plasticizers would be low in cost, compatible with the host polymer and be easily processed. For extending the lifetime of plasticized materials, the additive must have a low volatility and not leach from the host.
Application of ionic liquids as plasticizers for poly(methyl
The room temperature ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate, [C 4 mim] [PF 6] was found to be an efficient plasticizer for poly (methyl methacrylate), prepared by in situ radical polymerization in the ionic liquid medium; the polymers have physical characteristics comparable with those containing traditional plasticizers
Manufacturing pure cellulose films by recycling ionic liquids
Herein, by recycling green ionic liquids (ILs) as cellulose plasticizers, a green manufacturing strategy was investigated, in which PCFs, which can be used as flexible cellulose electronic substrates, were successfully manufactured.
Application of ionic liquids as plasticizers for poly(methyl
As compared to organic as well as inorganic PCM, ionic liquid PCM exhibit several excellent characteristics, including excellent thermal and chemical stability, superb solubility, large...
- Are ionic liquids a good plasticizer for poly (methyl methacrylate)?
- Room temperature ionic liquids (ILs) based on imidazolium salts, were found to be excellent plasticizers for poly (methyl methacrylate), with improved thermal stability, and the ability to reduce glass transition temperatures to near 0 °C.
- Are room temperature ionic liquids a plasticizer for poly (vinyl chloride)?
- Room temperature ionic liquids (ILs), based on ammonium, imidazolium and phosphonium cations, were studied as novel plasticizers for poly (vinyl chloride), PVC. All the ILs tested were able to produce flexible PVC.
- Can ionic liquids be used as plasticizers for CTA films?
- The use of ionic liquids as plasticizers for CTA films, as shown, reduces the worst-case degradation temperature to 230 °C. Other studies have found this behavior [ 73 ]. It is possible that this is due to the presence of residual chloroform and groups of unreacted ionic liquids that begin to decompose at low temperatures.

- Are hydrophobic ionic liquids efficient plasticizers of CTA film?
- As a result, the ILs synthesized could be regarded as efficient plasticizers of CTA film. The studied hydrophobic ionic liquids, [C 6 MIM] [PF 6] and [N 2226 ] [PF 6] retarded the aging process of cellulose triacetate films exposed to outdoor conditions.
- Are CTA films plasticized with ionic liquids based on imidazolium and ammonium cations?
- In summary, we have successfully developed CTA films plasticized with four ionic liquids based on imidazolium and ammonium cations. The resulting films have been distinguished by their high flexibility and transparency, high tensile strength, good thermal stability and excellent weather and fire resistance.
