<p>The surface roughness (μm) results of the study.</p>

Surface roughness and hardness measurements for 80 specimens of A-2000 maxillofacial silicone elastomer. The data compares non-filled samples with those filled with 3% or 10% silica or titanium dioxide nanofillers, both before and after two years of natural weathering. The dataset was created by Mohammed Mousa and published on figshare in April 2026.

Use Cases

• Compare the effect of silica versus titanium dioxide nanofillers on silicone surface properties based on the described experimental groups.
• Analyze the impact of long-term natural weathering on material hardness based on the two-year weathering test.
• Model the relationship between nanofiller concentration (3% vs. 10%) and surface roughness based on the described experimental design.
• Validate findings from profilometer and SEM surface analysis against Shore-A durometer hardness measurements.

Strengths

• Includes data for 80 total specimens across 10 distinct experimental conditions.
• Compares two key material properties (roughness and hardness) and two nanofiller types at two concentrations.
• Contains measurements from multiple instruments: profilometer, SEM, Shore-A durometer, and FTIR spectroscopy.

Limitations

• Row count and specific column names are unknown, requiring manual inspection after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred from the description.
