Hydroxyl (OH) and amino (NH₂) functionalized boron nitride nanotubes (f-BNNTs) were integrated into an epoxy resin (Epon828) to achieve improved mechanical properties. While raw BNNT-composites yielded the largest values for Young’s modulus and appeared to be well mixed, f-BNNTs were found to provide a superior combination of mechanical properties yielding improvements in strain at failure, tensile strength and toughness that were not observed using raw BNNTs. In particular, an increase of 21% in Young’s modulus is observed with 5 wt% of f-BNNT, and increases of 12, 21, and 49% are observed in tensile strength, failure strain, and toughness, respectively, with 2 wt% f-BNNT while a 34% increase in fracture toughness is observed with 3 wt% f-BNNT.

将羟基（OH）和氨基（NH ₂）功能化的氮化硼纳米管（f-BNNTs）集成到环氧树脂（Epon828）中，以提高机械性能。虽然原始BNNT复合材料的杨氏模量最大，并且似乎混合得很好，但发现f-BNNT提供了机械性能的优异组合，从而改善了使用原始BNNT时未观察到的断裂应变，拉伸强度和韧性。尤其是，使用5 wt％的f-BNNT时，杨氏模量增加了21％，而使用2 wt％的拉伸强度，破坏应变和韧性时，杨氏模量分别增加了12、21和49％。 f-BNNT，而3％（重量）的f-BNNT则使断裂韧性提高了34％。
