Cohesive force in a polymer
Cohesion (from Latin cohaesiō 'cohesion, unity'), also called cohesive attraction or cohesive force, is the action or property of like molecules sticking together, being mutually attractive. It is an intrinsic property of a substance that is caused by the shape and structure of its molecules, which makes the distribution of surrounding electrons irregular when molecules get close to one another, creati… WebNoteworthy, the adhesive strength of the main-chain degradable network polymer was varied from the level of PSA to structural adhesives by increasing the added amount of …

WebThe cohesive forces are associated with Van der Waals forces and hydrogen bonding that cause liquids such as water to withstand the separation. When a glass surface is poured with water, both adhesive and cohesive forces act on the surface of the water. Webcohesive properties of the adhesive, normally in shear, (ii) adhesive properties on a specific substrate, most commonly these tests are based on peeling a flexible strip of the adhesive from the desired substrate, and (iii) tackiness of the adhesive, i.e., its ability to stick after a short contact under light pressure.
