In general, as roughness of a surface increases, the contact angle in a Wenzel state will generally increase on hydrophobic surfaces and decrease on hydrophilic surfaces.
Next, the most promising candidates were studied in comparison with the control for their waterproofing properties by contact angle measurements, artificial weathering testing (QUV) according to the European standard EN11507 and evaluation tests for the effectiveness of water repellent coatings on wood, according to the ASTM D5401 standard ("Evaluation of Clear Water Repellent Coatings on Wood").
In this system, the performance of membranes was evaluated in terms of PWF, rejection, porosity, and contact angle, and the morphology of the membranes was analyzed by scanning electron microscopy (SEM).
The size of the water drop contact angle depends on the properties of the surface under observation and on various effects that appear during the measurement [6,10].
The water contact angles of the surface of the samples were measured with Static Contact Angle Measurement using the drop drop method (each sample was analyzed three times).
Surfaces treated with SuperCN Plus show water contact angles as high as 165[degrees].
Dynamic contact angle measurements were performed using a Dataphysics OCA 20 apparatus.
The initial contact angle progressively migrated forward as the slope increased, except that the initial contact angle between the 2.
Goniometry measurements showed a statistically significant difference in water contact angle between the two ELP/ELP-PA blends (Figure 6).
00264 gal) of purified water was dropped on each disk specimen, and the contact angle of the water drop was measured 1 minute later by a contact angle meter (EasyDrop systems, KRUSS GmbH).
Slide reagent dispersal and drop contact angle were measured to assess hydrophobicity and hydrophilicity of slides.
NeverWet causes water droplets to form a contact angle of up to 165 degrees, more than three times the contact angle of an untreated surface.
