This study explores the possibility related to the method of surface modification on MXene Ti3C2Tx. Surface modification has been explored previously to change the quality of the decomposition product of Ti3C2Tx in ceramic matrix composites. As a part of this experiment a new surface modification method was developed by mixing Ti3C2Tx directly with Al2O3/Y2O3 through hydrothermal treatment. This study also explores the effect of different etchant such as HF 48%, in-situ HF (max nominal 5.1%), and in-situ HF with hydrothermal treatment to the specific surface area of specimen and the result of surface modification formed on the specimen. Moreover, an oxidation test was carried out at a temperature of 1000°C to evaluate thermal stability of Ti3C2Tx after surface modification. Upon analysis of the obtained specimen revealed that Ti3C2Tx-Hydro produced the best MXene morphology visually. Then it was shown that hydrothermal treatment showed the potential to be an alternative method for MXene surface modification. After oxidation test it was confirmed that surface modification can increase thermal stability as shown by the decrease in weight gain after oxidation. MTi3C2Tx-Hydro showed the biggest improvement in thermal stability shown in this experiment.
