Regarding the current demand for controlling plastic pollution, recycling of polymer sounds a promising solution. However, recycling causes mechanical and thermal shortcomings in polymers. Addition of nanoparticles to recycled materials may overcome these shortcomings. Nanocomposites can be achieved either by blending or through polymerization. Sepiolite as a nanoparticle enhances the thermal properties of polymers. In this study, the effect of sepiolite as a nanoparticle has been investigated on the thermal and mechanical behavior of recycled high-density polyethylene (HDPE). Hardness, density, Vicat softening temperature, melt flow rate (MFR), and differential scanning calorimetry has been investigated on recycled HDPE containing different amount of sepiolite. Results showed that both the amount of recycled HDPE and the sepiolite content affect the mechanical and thermal behavior of samples. Increasing the amount of recycled component resulted in increasing of MFR, a slight increase in density, and decrease in Vicat softening point, hardness, melting temperature, and degree of crystallization. As an opposite effect of these to factors on crystallinity of HDPE, sepiolite content has better effects to be considered separately for each recycle content. Sepiolite can be introduced as a low-cost reinforcement filler in recycling industry for tuning new compositions based on process condition, or vice versa.

关于控制塑料污染的当前需求，聚合物的回收听起来是一个有前途的解决方案。但是，回收会导致聚合物的机械和热缺陷。将纳米颗粒添加到回收材料中可以克服这些缺点。纳米复合材料可以通过共混或通过聚合来实现。海泡石作为纳米颗粒可增强聚合物的热性能。在这项研究中，已经研究了海泡石作为纳米颗粒对回收的高密度聚乙烯（HDPE）的热和机械性能的影响。已对含有不同量海泡石的再生HDPE进行了硬度，密度，维卡软化温度，熔体流动速率（MFR）和差示扫描量热法的研究。结果表明，回收的HDPE的量和海泡石的含量都会影响样品的机械性能和热性能。回收组分的增加导致MFR的增加，密度的轻微增加以及维卡软化点，硬度，熔融温度和结晶度的降低。作为这些因素对HDPE结晶度的相反作用，海泡石含量具有更好的效果，对于每种循环含量，都应单独考虑。海泡石可以作为一种低成本的补强填料引入回收行业，用于根据工艺条件调整新的成分，反之亦然。熔化温度和结晶度。作为这些因素对HDPE结晶度的相反作用，海泡石含量具有更好的效果，对于每种循环含量，都应单独考虑。海泡石可以作为一种低成本的补强填料引入回收行业，用于根据工艺条件调整新的成分，反之亦然。熔化温度和结晶度。作为这些因素对HDPE结晶度的相反作用，海泡石含量具有更好的效果，对于每种循环含量，都应单独考虑。海泡石可以作为一种低成本的补强填料引入回收行业，用于根据工艺条件调整新的成分，反之亦然。
