Addition of fillers in polyurethane foams enhances the mechanical properties of polymeric foams. However, fillers can be loaded to a certain extent, as higher percentage of fillers in polymeric foam causes structural instability leading to the collapse of foam. In this article, we report the use of hollow glass microspheres as a possible co-filler which enables higher loading of nano-clay in flexible polyurethane foam. It has been observed that the structural and mechanical properties of nano-clay-loaded foams were found to cause instability at 5 wt% loading of nano-clay. Therefore, upon addition of hollow glass microspheres in 5 wt%, nano-clay-loaded polyurethane foam shows remarkable enhancement in terms of stability and mechanical properties of the resultant foams. A 100-fold increment in tensile strength has been observed for 2 wt% hollow glass microspheres and 5 wt% nano-clay-loaded flexible polyurethane foams as compared to conventional (unloaded) polyurethane foams.

使用空心玻璃微球增强高负载纳米粘土基柔性聚氨酯泡沫的稳定性

在聚氨酯泡沫中添加填料可增强聚合物泡沫的机械性能。然而,填料可以在一定程度上加载,因为聚合物泡沫中较高百分比的填料会导致结构不稳定,从而导致泡沫破裂。在本文中,我们报告了使用中空玻璃微球作为可能的辅助填料,它可以在软质聚氨酯泡沫中增加纳米粘土的负载量。已经观察到,纳米粘土负载的泡沫的结构和机械性能在纳米粘土负载量为 5 wt% 时会导致不稳定。因此,在添加 5 wt% 的空心玻璃微球后,纳米粘土负载的聚氨酯泡沫在所得泡沫的稳定性和机械性能方面表现出显着增强。
