Recently we have fabricated a biobased nanocomposite films from PLA/CNC by effective blending then solution casting method followed by EIPS. But for a perticular composite it has clerly been found a large agglomeration additionally poor adhesion during compounding indeed whereas it exhibited less thermal stability & lower crystalinity index. But i am not sure about the actual reason behind the sence but suspect that the large agglomeration & poor adhesion is guilty for it, is it?
What do you think about it?
I would say the same, yes. The agglomeration caused by increasing the loading of particles and/or the surface energy difference between the components (thermodynamic aspect) could be the reason for it. Because with the existence of agglomerate and poor interfacial adhesion/wettability, most of the material properties will be deteriorated. However, you can try with a lower loading of particles and/or using an emulsifier or a compatibilizer in order to improve the interfacial adhesion to see the difference. Best of luck.
