主　　题：3D printing MXene Nanocomposites Stretchable conductors 

摘      要：Additive manufacturing has rapidly evolved over recent years with the advent of polymer inks and those inks containing novel *** compatibility of polymer inks with nanomaterial inks remains a great *** yet effective methods for interface improvement are highly sought-after to significantly enhance the functional and mechanical properties of printed polymer *** this study,we developed and modified a Ti_(3)C_(2) MXene ink with a siloxane surfactant to provide compatibility with a polydimethylsiloxane(PDMS)*** rheology of all the inks was investigated with parameters such as complex modulus and viscosity,confirming a self-supporting ink behaviour,whilst Fourier transform infrared spectroscopy exposed the inks’reaction *** modified MXene nanosheets have displayed strong interactions with PDMS over a wide strain *** electrical conductivity of 6.14×10^(−2) S cm^(−1) was recorded for a stretchable nanocomposite conductor containing the modified MXene *** nanocomposite revealed a nearly linear stress-strain relationship and a maximum stress of 0.25 *** 5%strain,the relative resistance change remained below 35%for up to 100 cycles,suggesting high flexibility,conductivity and mechanical *** study creates a pathway for 3D printing conductive polymer/nanomaterial inks for multifunctional applications such as stretchable electronics and sensors.
