Contact Angles high density polyethylene

Fig. 7. Dependence of the contact angle of water on the preirtadiation dose. Acrylamide was polymerized with a 10 wt- % solution for 1 h at 50 C in the absence of Fe. O low-density polyethylene high-density polyethylene...

The same drop could also be used to determine the receding contact angle and the water wettability of the biopolymer adsorbed on the solid. We employed glossy high-density polyethylene slabs as the solid substrate.
