Investigation of wetting behavior of HDPE reinforced with nanoscopic 1D/2D filler system using contact angle goniometry

Current work investigates wetting abilities of High Density Polyethylene (HDPE) based composites and hybrids. The samples were prepared by varying weight fractions of Multi Walled Carbon Nanotubes (MWCNTs) and hexagonal-Boron Nitride Nanoplatelets (h-BNNPs). The technique used for fabrication was melt mixing followed by injection moulding process. The wetting abilities of the test samples were assessed using an in situ contact angle measurement test setup. The test results confirmed the superior wetting abilities by 0.25 MWCNT/0.15 BNNP hybrid composite. A comparison between angle of contact and surface roughness of test samples was also presented. It was concluded that rough surface tends to more hydrophobic then smoother surfaces.
