“…28 When incorporating GO nanosheets into the PMMA resin, the movement of a molecular chain hindered deformation, reducing strain recovery during the unloading period. 29 However, the addition of 0.025 wt/wt.% and 0.05 wt/wt.% GO increased the nanohardness and elastic modulus of GO1 and GO2 compared to Neat-PMMA, but the values were not statistically different. This may be attributed to the low-loading of GO in PMMA.…”

The purpose of this laboratory study was to formulate graphene oxide (GO) nano-sheets and characterize composites of homogenously dispersed GO sheets in poly(methyl methacrylate) (PMMA) acrylic resin of two groups, i.e., with 0.025 wt/wt.% GO (GO1-group) and 0.05 wt/wt.% GO (GO2-group). A large array of surface, mechanical and dynamic mechanical properties, including creep, recovery, stress relaxation behaviour and temperature and frequency sweep of the formulated bone cements were further characterized. Analysis of variance test results (p = 0.05, n = 5) indicated that the nanohardness and elastic modulus of the experimental groups were not significantly different from those of the control. Micro-computed tomography results showed high porosity in the experimental groups. The compressive strength significantly increased both in GO1- and GO2-group under dry and wet storage conditions. The dynamic mechanical properties suggest a desirable role of GO in polymerization with PMMA. The produced GO-PMMA composites exhibited the expected characteristics, so their use in developing low-loading bone cement composites appears to be promising.

The objective of this study was targeted to synthesize and characterize a carbon nanotubes (CNTs) incorporated poly(methyl methacrylate) (PMMA)-based denture polymer. Two experimental denture base polymers were fabricated either by incorporating single-walled CNTs (SWCNTs) (SW-group) or multi-walled CNTs (MWCNTs) (MW-group). In both groups, 0.5 wt% of the CNTs were incorporated into MMA monomer. Using a commercially available heat-cured PMMA (Interacryl Hot, Interdent, Opekarniska, Slovenia), a polymer-to-monomer ratio of 3:1 was used to fabricate the specimens (14 × 14 × 3 mm3 in dimensions) of the control group (without CNTs) (C-group) and the experimental groups (either SWCNT–PMMA or MWCNT–PMMA) ( n = 30, N = 90). Physical, mechanical, thermal, and rheological attributes of the tested materials were assessed. The data were statistically analyzed using SPSS version 21.0 (SPSS®, Chicago, IL, USA) and results were explored with one-way ANOVA. Incorporation of CNTs changed the surface morphology and topography of the PMMA specimens. No thermal changes were observed among C-, SW-, and MW-groups. Conversely, the hardness, elastic modulus and wear resistance were improved in both SW-group and MW-group. Additionally, the dynamic mechanical analyzer showed improvement in storage modulus in SW-group, affirming the load transfer capability of SW–PMMA composite. The CNT–PMMA composite might favorably be used as a potential denture base polymer.

Utilization of waste or garbage in Indonesia continues to be carried out in line with the increasing number of which is used as a filler material in making composites. This study aims to determine the effect of composite material composition made from fly ash coal, rice husk charcoal and HDPE plastic on compressive strength, water absorption and density of the material. This research was conducted as an experimental study that had been carried out by means of laboratory tests. The composition used was 30%: 5%: 65%, 25%: 10%: 65%, 20%: 15%: 65%. Specimens were made to ASTM D695 standards for press testing. The results of this study indicate that the value of the compressive strength obtained at the composition of 30%: 5%: 65% is equal to 1.96 N / mm2, the value of water absorption in the largest composite material is at the composition of 20%: 15%: 65%, which is equal to 2,0283%, as well as for the density value of the largest composite material at the composition of 30%: 5%: 65% which is equal to 1.4692 g / cm3.Keywords: Fly ash coal, rice husk charcoal, HDPE Plastic, press, water absorption, density
