MXene modified by stearic acid (Ti 3 C 2 T x -g-SA) is incorporated into poly(lactic acid) (PLA) matrix to prepare Ti 3 C 2 T x -g-SA/PLA composites. The effects of Ti 3 C 2 T x -g-SA to pure PLA are investigated, including crystallization, mechanical, and thermal properties. Fourier transform infrared spectroscopy and X-ray diffraction analyses confirm that Ti 3 C 2 T x interlayer is successfully intercalated by SA, and the interlayer spacing of Ti 3 C 2 T x is increased. Differential scanning calorimetry illustrates that the cold crystallization enthalpy (ΔH cc ), melting enthalpy (ΔH m ), and crystallinity (X c ) of Ti 3 C 2 T x -g-SA/PLA composites are improved by the plasticization and heterogeneous nucleation effect of Ti 3 C 2 T x -g-SA. Specially, the Ti 3 C 2 T x -g-SA/PLA composites exhibit excellent mechanical properties at an appropriate content of the Ti 3 C 2 T x -g-SA. Compared with pure PLA, the elongation at break of the Ti 3 C 2 T x -g-SA/PLA composite is increased 5.9-fold (up to 131.6%) when only containing 0.5 wt % Ti 3 C 2 T x -g-SA. Besides, the Ti 3 C 2 T x -g-SA/PLA composites exhibit good thermal stability in the low loading (lower than 1 wt %) of Ti 3 C 2 T x -g-SA.

“…The method is solvent-free, flexible, economical, and environmentally friendly and therefore could be used in scalable manufacturing systems. The different types of polymers, such as ultrahigh molecular weight polyethylene (UHMWPE), [81] (linear low-density polyethylene) LLDPE, [82] polyurethane (PU), [83] polystyrene (PS), [84] polyaniline (PANI), [35] and polyvinylidene fluoride (PVDF), [60] etc. have been filled by MXenes through hot-pressing techniques.…”

MXenes are recently discovered 2D nanomaterial with superior mechanical, thermal, and tribological properties, being commonly employed in a wide variety of critical research areas, ranging from cancer therapy to energy and environmental applications. Due to their special properties, such as mechanoceramic nature with excellent mechanical performance, thermal stability and rich surface properties, MXenes have tremendous potential as advanced composite structures, especially those based on polymers due to a great affinity between macromolecules and the terminating groups of 2D MXenes. MXenes have been extensively explored in metal matrix nanocomposites as well as in solid‐ or liquid‐based lubrication systems owing to the 2D structure and antifriction characteristics. The purpose of the this paper is to provide a comprehensive insight into the material, mechanical, and tribological properties of the MXene nanolayers with discussions on the recent advancements attained from MXene‐reinforced nanocomposites starting with the synthesis, fabrication techniques, intricacies of the underlying physics and mechanisms, and finally focusing on the progress in computational studies. This analysis of MXene‐based composites will stimulate an emerging field with innumerable opportunities and ample potentials to produce newfangled materials and structures with targeted properties.

“…While these works focus on the effects on the physical properties of MXene/polymer composites, studies on their crystallization processes have been less reported. Cao et al [ 26 ] prepared 2D MXene nanosheets/linear low-density polyethylene (LLDPE) by melt mixing to investigate the crystallization process. They found that 2 wt% MXene can enhance the crystallization rate of LLDPE while excessive amounts of MXene such as 4 wt% would retard the rate.…”

The effects of MXene on the crystallization behavior of β-nucleated isotactic polypropylene (iPP) were comparatively studied. The commonly used MXene Ti3C2Tx was prepared by selective etching and its structure and morphology were studied in detail. Then MXene and a rare earth β-nucleating agent (NA) WBG-II were nucleated with iPP to prepare samples with different polymorphic compositions. The crystallization, melting behavior, and morphologies of neat iPP, iPP/MXene, iPP/WBG-II, and iPP/MXene/WBG-II were comparatively studied. The crystallization behavior analysis reveals that a competitive relationship exists between MXene and WBG-II when they were compounded as α and β nucleating agents. In the system, the β-nucleation efficiency (NE) of WBG-II is higher than α-NE of MXene. The β-phase has relatively low thermal stability and would transform to α-phase when cooled below a critical temperature.
