Contact angle measurements were performed for a five-ring polyphenyl ether isomeric mixture on M steel in a dry nitrogen atmosphere. Two different techniques were used: (1) a tilting-plate apparatus, and (2) a sessile drop apparatus.

Measurements were made for the temperature range 25 to ° by: 5. Get this from a library. Contact angle and surface tension measurements of a five-ring polyphenyl ether. [William R Jones; Lewis Research Center.].

Alspach, P. Hell and D.J. Miller (Eds.) In recent years, there has been an explosion of interest in the science of adhesion. Despite its multidisciplinary and undoubtedly industrial character, the wealth of phenomena to be found in the study of adhesion has drawn researchers from many seemingly disparate scientific disciplines.

These lubricants included polyphenyl ethers, mineral oils, a. synthetic paraffin, a silicone, and a polyether. A polyphenyl ether exhibited the highest surface tension ( In general, the wettability of a surface can be characterized by the contact angle (CA).

Multifuntional surfaces with special wettability have attracted a lot of interest in both fundamental research and industry applications over the last two decades [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15].The surface with a water droplet CA less than 90° and above 90° is commonly defined as hydrophilic and.

For instance, considering a supercooled liquid nucleating on top of an ideal planar surface offered by the foreign phase, we obtain the so-called Young’s relation where θ is the contact angle, namely, a measure of the extent to which the crystalline nucleus wets the foreign surface.

Thus, the contact angle determines whether and how much it. Polymer degradation is a change in the properties—tensile strength, color, shape, etc.—of a polymer or polymer-based product under the influence of one or more environmental factors such as heat, light or chemicals such as acids, alkalis and some changes are usually undesirable, such as cracking and chemical disintegration of products or, more rarely, desirable, as in.Enabling Your Technology Contct s toEBy • 5 Critical surface Tension and adhesion While the contact angle of water on a substrate is a good indicator.For example, the contact angle defined in Fig.

2 influences fatigue life and the temperatures developed during bearing operation. Spherical balls enclosed between two concentric rings permit the rings to rotate relative to each other, whilst supporting a radial load; this is the essence of a ball bearing.
