Surface Roughness, Hardness and FTIR of the Modified Soft Liner with Different Metal Oxide Nanoparticles

Abstract

Aims: To study the effect of metal oxide nanoparticles (MgO, ZrO2, ZnO) on acrylic based soft liner surface properties and FTIR. Materials and Methods: Acrylic-based soft-liner specimens were prepared by adding three different concentrations (0.5, 1, and 2) %wt of metal oxide nanoparticles (MgO, ZrO2, ZnO). A disk-shaped specimens with 30mm diameter and 3mm thickness were prepared for shore (A) hardness test to evaluate the surface hardness of modified soft liner. The surface roughness of soft-liner samples (10X10X2mm) was tested by a profilometer. FTIR analysis was conducted to evaluate chemical reaction that may occur between acrylic-based soft liner and nanoparticles. Results: there were no chemical reaction carried out between soft liner and metal oxide nanoparticles at different concentration-surface hardness (shore A) was increased as nanoparticles concentration increased in modified resin. Nanoparticles with 1 and 2% concentration incorporated in soft liner had lower surface roughness value. Conclusions: Metal oxide nanoparticles have improved the surface texture of acrylic-based soft liner, while the hardness of modified soft liner was increased with nanoparticles concentration increases. ‫الخالصة‬ ‫األهداف‬ : ‫ال‬ ‫الدراسةةةل‬ ‫تهدف‬ ‫د‬ ‫دا‬ ‫ماسةةةاد‬ ‫اكاسل‬ ‫ال‬ ‫الماةةةانان‬ ‫ال‬ ‫تر‬ ‫راسةةةل‬ MgO ، ZrO2 ، ZnO ‫عل‬) ‫اكل‬ ‫ا‬ ‫ب‬ ‫سة‬ ‫خصةاص‬ ‫قم‬ ‫ال‬ ‫النلكل‬ ‫االسةا‬ ‫ذان‬ ‫االملسلاك‬ ‫ي‬. ‫المواد‬ ‫و‬ ‫طرا‬ ‫ئ‬ ‫العمل‬ ‫ق‬ ‫النلكل‬ ‫اكل‬ ‫ا‬ ‫ان‬ ‫عا‬ ‫إعداد‬ ‫تم‬ : ‫اد‬ ‫الن‬ ‫ةاد‬ ‫ما‬ ‫كاكاسل‬ ‫ةانان‬ ‫سا‬ ‫ةاةل‬ ‫اإض‬ ‫ملسلاك‬ ‫ا‬ MgO ، ZrO2 ، ZnO ‫ختلفل‬ ‫تلاماز‬ ‫ل‬ ‫واثال‬) 0.5 ، 1 ، 2 ٪ ‫ل‬ ‫ةكص‬ ‫لة‬ ‫عل‬ ‫ع‬ ‫نل‬ ‫ال‬ ‫ةال‬ ‫تحضة‬ ‫تم‬ .) ‫الاز‬ ‫ن‬ ‫ل‬ ‫واق‬ 30 ‫ةنك‬ ‫وااة‬ ‫لم‬ 3 ‫الختبار‬ ‫لم‬ ‫ب‬ ‫ة‬ ‫االسة‬ ‫ةالال‬ ‫صة‬ A shore ‫النلكل‬ ‫قم‬ ‫ال‬ ‫اكل‬ ‫ا‬ ‫ان‬ ‫عا‬ ‫ب‬ ‫ة‬ ‫سةة‬ ‫ةاكل‬ ‫خعةة‬ ‫ةط‬ ‫ةحصةة‬. ‫دلل‬ ‫الن‬ ‫النلكل‬ ‫قم‬ ‫ال‬ ‫اكل‬ ‫ا‬ ‫ب‬ ‫ة‬ ‫سةة‬ ‫ةالال‬ ‫صةة‬ ‫لتقاام‬) ‫اقااسةةان‬ 10 X10 X2 ‫ااسةةتخدا‬) ‫لم‬ ‫ب‬ ‫سةة‬ ‫ا‬ ‫تباسن‬ ‫قاا‬ ‫تحلاص‬ ‫أسلي‬ ‫د‬ ‫و‬.
