Scientific Research Applications

Non-Isocyanate Polyurethane Synthesis

Bis(hexafluoroisopropyl) carbonate and related bis(cyclic carbonates) play a crucial role in the synthesis of non-isocyanate polyurethanes (NIPUs). These compounds are formed through reactions with diamines, providing an alternative to conventional polyurethanes which typically require toxic phosgene or isocyanates. This method not only offers a safer and more environmentally friendly approach but also produces polyurethanes with significant molecular weights and narrow polydispersity indexes. The NIPUs exhibit desirable properties such as glass transition temperatures and good thermal stability (Sheng et al., 2015), (Chen et al., 2015), (Zhang et al., 2017).

Advanced Materials for Biomedical Applications

Bis(cyclic carbonate) derivatives, including those derived from bis(hexafluoroisopropyl) carbonate, have found extensive applications in the biomedical field. These compounds are integral in designing biodegradable polymers with tailored multi-functional properties. The polymers formed, such as polycarbonates, exhibit high drug loading capacities and excellent biocompatibility, making them suitable for various biomedical applications including drug and nucleic acid delivery (Ansari et al., 2021).

Flame Retardant Additives

Compounds like Bis(2,2,2-Trifluoroethyl) Ethylphosphonate, a variant of bis(hexafluoroisopropyl) carbonate, are utilized as flame retardant additives to improve the safety of materials, particularly in lithium-ion batteries. These additives significantly suppress the flammability of electrolytes, demonstrating their effectiveness in enhancing safety without negatively impacting the electrochemical performance of the batteries (Zhu et al., 2015).

Synthesis of Aromatic Condensation Polymers

In the field of polymer science, bis(hexafluoroisopropyl) carbonate and its derivatives contribute to the synthesis of aromatic polyethers and copolyethers. These polymers exhibit unique properties such as solubility in various organic solvents, formation of colorless and transparent films, and increased contact angles to water with higher fluorine content. Their applications extend to areas requiring specific optical and dielectric properties (Saegusa & Koizumi, 2005).

Electronics and Memory Devices

In electronic applications, functional polyimides containing hexafluoroisopropyl groups demonstrate nonvolatile memory behavior. These materials show promising characteristics such as electrical bistability and significant ON/OFF current ratios, making them suitable for memory devices in electronic applications. The molecular structures and charge transfer mechanisms in these polyimides contribute to their functionality (Tian et al., 2011).
