Commercial Pebax®1657 (consisting of 60 wt% PEO and 40 wt% PA6) was purchased from Arkema Inc. A mixture of ethanol and water (70/30 wt%) was used as a solvent for Pebax®1657. Ammonia water (NH3·H2O, 25%) and tetraethyl orthosilicate (Si(OEt)4, TEOS, 98%) were supplied by Feng chuan Chemistry Co., Ltd. (Tianjin, China) and Aldrich, respectively. Pristine HNTs were provided by Henan Xianghu Environmental Protection Technology Co., Ltd. (Henan province, China). Polystyrene sulfonate sodium salt (PSS, MW = 70,000) was provided by Sigma-Aldrich. Hydrofluoric acid (HF) and Ti3AlC2 powder were purchased from Sigma-Aldrich. Ethanol, hydrogen peroxide, hydrochloric acid, phosphoric acid, dimethyl sulfoxide (DMSO), sulfuric acid, and KMnO4 were provided by Kewei Chemistry Co., Ltd. (Tianjin, China). Deionized water was used throughout the experiment. The polymer and other chemicals were used as received without further treatment.
Ti3alc2 powder
Manufactured by Merck Group
Ti3AlC2 powder is a ceramic material composed of titanium, aluminum, and carbon. It is a member of the MAX phase family of materials, characterized by a layered hexagonal crystal structure. The powder form of this material is suitable for various industrial and research applications that require its unique properties, such as high thermal and electrical conductivity, oxidation resistance, and machinability.

Cu-intercalated
Ti3C2Tx and Ti3c2Tx MXene were synthesized
following the Ghidiu et al.
procedure.39 (link),40 (link) Specifically, 1 g of Ti3AlC2 powder (Carbon-Ukraine, <44 μm particle
size) was gradually added to a 10 mL solution of 10 wt % hydrofluoric
acid (HF, Sigma-Aldrich, 48 wt %) and ∼1.1 g of LiCl (with
a molar ratio 5:1 to Ti3AlC2). Then, the mixture
was stirred at 300 rpm for 24 h at room temperature. This step leads
to the simultaneous selective removal of the Al layer from Ti3AlC2 and the intercalation of Li+ ions
in between Ti3C2Tx layers. Next, the wet sediment was divided into two batches and
washed 3 times with 6 M HCl (hydrochloric acid, Sigma-Aldrich, 37%)
with a ratio of 0.5 g of MXene to 40 mL of HCl solution. After each
washing, centrifugation at 3500 rpm for 5 min was performed. This
yielded the Ti3C2Tx MXene in which intercalated Li+ ions were exchanged by
H3O+. Finally, the sediment was washed with
40 mL of MiliQ water at least 4 times until pH 5 was reached. For
the control sample, non-intercalated “pristine” Ti3C2Tx, the wet sediment
was collected directly after DI washing and dried and used as is for
the experiments.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
