研究目的
Investigating the development and properties of 3D printable multifunctional ionic gels incorporating ionic liquid in the thiol–ene network.
研究成果
The study successfully developed multifunctional T-IGs with variable structures and properties via conventional and optical 3D printing processes. The mechanical and conductive properties were tunable based on the end-crosslinker type, IL content, and monomer chain length. The T-IGs exhibited high thermal stability and were successfully 3D printed, showing potential for applications in MEMS, microfluidics, and sensors.
研究不足
The study focuses on a specific type of ionic liquid and thiol–ene network, which may limit the generalizability of the findings to other systems. The mechanical and conductive properties are highly dependent on the composition, which requires precise control.
1：Experimental Design and Method Selection:
The study utilized a one-step photo polymerization process to develop thiol-ionic gels (T-IGs) by incorporating ionic liquid (IL) into the thiol–ene network. The mechanical and conductive properties were investigated based on IL content, end-crosslinker functionalities, and monomer chain length.
2：Sample Selection and Data Sources:
Thiol end-crosslinkers (3T, PTMB, DPMP) and acrylate monomers (BDDA, HDDA, NDDA) were used with IL BMImFSI.
3：List of Experimental Equipment and Materials:
UV chamber for photo-polymerization, Jasco FTIR 460 plus spectrometer for infrared spectra, STA-1150 for mechanical strength, Seiko Instruments thermogravimetry/differential thermal analyzer for TG measurements, HIOKI 3532–80 for conductivity measurements.
4：Experimental Procedures and Operational Workflow:
The pre-gel solution was prepared by mixing thiol end-crosslinkers, acrylate monomers, and IL, followed by UV irradiation for polymerization.
5：Data Analysis Methods:
Mechanical properties were analyzed using compression tests, thermal stability via TGA, and conductivity through impedance spectroscopy.
