AB  - U ovom radu je ispitan uticaj rastvarača i načina procesiranja ojačanja na mehanička svojstva nanokompozita poli-(metil metakrilat) PMMA-Ti3C2Tx makseni. Korišćen je maseni udeo ojačanja 1% i dve vrste rastvarača za pripremu uzoraka: dimetilformamid (DMF) i aceton (Ac). Za delaminaciju maksena korišćeni su dejonizovana voda i DMF. Na FTIR spektrima dobijenih uzoraka uočava se dodatan pik na 1675 cm-1 što ukazuje da je DMF zaostao u materijalu tokom sušenja. Rezultati mikroindentacije pokazuju da uzorci gde je maksen delaminisan u dejonizovanoj vodi a PMMA rastvaran u acetonu imaju 74,46% veći redukovani modul elastičnosti, što je podržano i SEM snimcima gde se uočava bolja dispergovanost maksena.
AB  - In this paper, the influence of solvents and reinforcement processing methods on the mechanical properties of nanocomposite poly-(methyl methacrylate) PMMA-Ti3C2Tx MXene was investigated. A weight fraction of reinforcement was 1% and two types of solvents were used for sample preparation: dimethylformamide (DMF) and acetone (Ac). Deionized water and DMF were used to delaminate the MXene. An additional peak at 1675 cm-1 was observed on the FTIR spectra of the obtained samples, which indicates that some amount of DMF remained in the material after drying. The results of microindentation show that samples where MXene was delaminated in deionized water and PMMA dissolved in acetone had a 74.46% higher reduced modulus of elasticity, which is supported by SEM images where better dispersion of MXenes is observed.
