Physical: Surface Energy and Contact Angle [PRA Coatings Technology Centre] The contact angle and the surface tension of the liquid can then be used to calculate the surface energy of the substrate. Surface Tension and Contact Angle Measurements on Liquids page. This is not the most accurate method of measuring contact angles and we only recommend it in cases where you wish to determine the contact angle of a coating applied to only one side of a substrate. www.pra.org.uk /technical/testingphysicalsurfacetension.htm

CAM-FILM-T Contact Angle Meter The water contact angle on a uniform film surface depends on a specific property of the surface: wetting tension measured in dyne/cm. The higher the wetting tension of the film, the better its wettability and the smaller the contact angle. It utilizes a more analytical and repeatable water contact angle method of measuring wetting tension. www.wayneassoc.com /cam.htm

Standard Test Method for Corona 6.1 The wetting tension of a polymer film in contact with a drop of liquid in the presence of air is a function of the surface energies of both the air-film and film-liquid interfaces; any trace of surface-active impurities in the test liquid or on the film may affect the results. Because this test method and Test Method D 2578 use different test liquids, it is impossible to equate a water contact value to a single wetting tension value. 13.1 Report the instrument used, number of readings, average value of the contact angle measurements and standard deviation, wetting tension value found in the conversion chart, temperature, humidity, and any comments and observations. www.wayneassoc.com /standard_test.htm

Experiments on Surface Phenomena and Colloids This height depends by a number of factors such as the surface tension of the liquid, the contact angle liquid/capillary, the radius of the capillary, the density of the liquid, the acceleration of gravity. This is due to the fact that the surface tension of the normal water is high and it tends to draw the water molecules into the main body of the water, to the point where the thickness of the bubble wall is too thin to remain intact and quickly bursts. The surface tension (T) is given by the force (F) divided by the width (W) of the membrane, divided again by two because it is necessary to keep into account the membrane possess two surfaces. www.funsci.com /fun3_en/exper2/exper2.htm   (11152 words)

Sexual Tension:  Want To But Can't For me, the sexual tension and attraction between my hero and heroine is a delicate mix of "want to but can't" (physical contact) and each characters emotional stakes (emotional contact). Creating wonderful sexual tension between my characters was one of the hardest things for me to learn as a writer. I randomly added passages of intense attraction between my hero and heroine in scenes where it wasn't appropriate to the story or my characters and their conflicts. www.hodrw.com /sexualtensionwantobutcant.htm   (11152 words)

An Analysis of Contact Angle Measurement Contact angle measurement (CA) is a simple-to-adopt method for surface analysis related to surface energy and tension. When drawing a tangent line from the droplet to the touch of the solid surface, the contact angle is the angle between the tangent line and the solid surface. Contact angle describes the shape of a liquid droplet resting on a solid surface. www.p2pays.org /ref/13/12920.htm   (11152 words)

contact angle, fibro system The contact angle measurement is a precise empirical tool to determine the interaction between a liquid (surface tension) and a substrate (surface free energy). Wetting can be measured as contact angle, which is formed by the substrate and the tangent to the surface of the liquid droplet at the contact point marked as "C". It must be emphasised that contact angle is not a property of the liquid or the substrate but the interaction between the two. www.fibro.se /wetting.html   (592 words)

Contact angle measurements Contact angles on polymer surfaces are not only influenced by the interfacial tensions according to Young& equation but also by many other phenomena, such as surface roughness, chemical heterogeneity, sorption layers, molecular orientation, swelling, and partial solution of the polymer or low-molecular constituents in the polymer material. Contact angles of liquids on polymer surfaces are widely used to predict wetting and adhesion properties of these solids by calculating their solid-vapour surface tension. As in the case of sessile liquid droplets, the contact angle of the captive bubble is normally measured by the conventional goniometer technique. www.ipfdd.de /research/res12/adsa_p.html   (592 words)

Gardco - Pocket Goniometer The contact angle is a function at the liquid's surface tension and the surface "free" energy at the substrate. Contact angle measurement is a reliable method to characterize the interaction between a liquid and a surface. The wetting hysteresis of a surface is characterized by the advancing/receding contact angles describing the wetting/de-wetting properties at a surface. www.gardco.com /goniometer.html   (592 words)

Contact_Angle The amount absorbed is a function of the viscosity, density and surface tension of the liquid, the material constant of the solid, and the contact angle of the interaction. This contact angle, which is obtained from data generated as the probe advances into the liquid, is the advancing contact angle. Contact angle can be assessed directly by measuring the angle formed between the solid and the tangent to the drop surface. www.ksvinc.com /contact_angle.htm   (592 words)
