Optimized UHMWPE/BaTiO3 Composite

Popis výsledku v původním jazyce

Based on the results of mechanical nad tribological testing composites with 5% of BaTiO3 was identifiet as promising material for load bearing aplications. Nanoparticles used in that formulation was considered further for surface functionalisation with (3-aminopropyl) triethoxysilane (APTES) via a reflux reaction setup. The objective of the functionalization was to improve nanoparticle dispersion and enhance interfacial bonding with UHMWPE, thereby addressing challenges associated with agglomeration of nanoparticles. The BaTiO3 was functionalised with 5 different concentrations of additives. Activated nanoparticles were incorporated into the UHMWPE matrix to fabricate new composites using compression molding. Based on tribological and mechanical characteristics the composite with BaTiO3 activated in 4 % solution of APTES is optimal.

Technické parametry

For this work, UHMWPE (powder grade GUR 4120) was used as a matrix and purchased from Celanese company with a molecular weight of 4.7x106g/mol, and a density of 0.93g/cm3. Barium titanate (pure; 99.95%, particle size 280nm, tetragonal) was bought from Nanografi Nano Technology Turkey as a nanofiller. Composites were prepared as desks 100x80 mm and with 2 mm thickness. The tensile strength achieved for the optimized composite was 35 MPa. During tribological testing with Al2O3 counterbody COF was 0.11 and the specific wear rate was 2,61E-06 mm^3/mN.

Ekonomické parametry

The material cost of one desk can be estimated to be 200 CZK primarily due to the price of BaTiO3. The price of APTES for the functionalization of material of a single desk is around 80 CZK. Based on the above-mentioned numbers, the price of the single desk of optimized composite can be put at around 280 CZK. This doesn't include the price of used energy, cost of labor, and depreciation of machines.
