A thrust on improvement of different properties of polymer has taken a contemporary route with advent of nanofillers. Although several nanofillers are existent; MultiWalled Carbon Nanotubes- (MWCNTs) and h-Boron Nitride nanoplatelets-(h-BNNPs) unique combination of 1D and 2D dimensional geometry aids an advantage of B-C-N triad elemental effects on properties of tested samples. The current study aims to investigate the effects of MWCNT and h-BNNP reinforcement in High Density Polyethylene (HDPE) for high load bearing areas of medical applications requiring both elastic and viscous behavior. The results were analyzed keeping a view of its application in areas like HDPE based fracture fixation plates, acetabular cups and others. The composite and hybrid samples with different loadings were prepared after surface modification of nanofillers by mechanical mixing and molding technique. The dynamic nano-mechanical properties like storage modulus, loss modulus and tan delta were assessed for each sample during frequency swept from 10 to 220 Hz. The viscoelastic properties like h_c/h_m, H/E, elastic-plastic deformation were investigated and evaluated. At a frequency of 10 Hz, the storage and loss modulus of 0.1 CNT increased by 37.56% and decreased by 23.52% respectively on comparison with pure HDPE. This infers a good elastic as well as viscous behavior. Overall elastic behavior of 0.1 CNT was confirmed from tan delta evaluation. The interaction between B-C-N elemental triad had significant effect on creep strength, visco-damping property (h_c/h_m and H/E), elastic plastic displacement and pile-up and sink-in behavior. Highest creep strength and visco-damping property was exhibited by 0.25 CNT/0.15 BNNP hybrid. The elastic-plastic displacement of hybrid composite was noted as least, which decreased by 30% on comparison with pure HDPE. It can be inferred that presence of 1D-MWCNT and 2D-h-BNNP had significant effect on important dynamic viscoelastic and creep properties of HDPE based hybrid composites.

随着纳米填料的出现，改进聚合物不同性能的努力已走上了一条当代路线。尽管存在几种纳米填料；一维和二维三维几何结构的独特结合是多壁碳纳米管（MWCNTs）和h-硼氮化物纳米板（h-BNNPs）的独特组合，有助于BCN三元组元素对被测样品的性能产生影响。当前的研究旨在调查在需要弹性和粘性行为的医疗应用的高承载区域中，MWCNT和h-BNNP增强在高密度聚乙烯（HDPE）中的作用。分析了结果，并保留了其在基于HDPE的骨折固定板，髋臼杯等领域的应用前景。通过机械混合和成型技术对纳米填料进行表面改性后，制备了具有不同负载量的复合样品和杂化样品。在从10到220 Hz扫频期间，评估了每个样品的动态纳米力学性能，如储能模量，损耗模量和tanδ。像h一样的粘弹性_c / h _m，H / E，弹塑性变形进行了研究和评价。在10 Hz的频率下，与纯HDPE相比，0.1 CNT的储能模量和损耗模量分别增加了37.56％和减少了23.52％。这推断出良好的弹性以及粘性行为。由tanδ评估证实了0.1 CNT的总体弹性行为。BCN元素三单元组之间的相互作用对蠕变强度，粘阻尼特性（h _c / h _m和H / E），弹性塑性位移以及堆积和下沉行为。0.25 CNT / 0.15 BNNP杂化体表现出最高的蠕变强度和减粘特性。杂化复合材料的弹塑性位移最少，与纯HDPE相比降低了30％。可以推断，1D-MWCNT和2D-h-BNNP的存在对基于HDPE的杂化复合材料的重要动态粘弹性和蠕变性能具有重要影响。
