Regular surface roughness could be created on the of a pressure-sensitive adhesive (PSA) film through Marangoni flow during drying process. Therefore, tailoring both and bulk characteristics PSA consequently its adhesion strength expected by controlling conditions. Herein, properties water-based dried at various temperatures humidities were scrutinized. Increase in temperature improved to poly(...

A new Ultra Violet (UV) curable solution acrylic polymer based technology has been under development for manufacturing optically clear pressure sensitive adhesives. Monomers, functional groups, and formulating components can be selected to modify and tailor product properties for specific optically clear end uses. Refractive index, outgassing, heat resistance, and humidity resistance among othe...

A simple model for the peeling process of pressure-sensitive adhesive tape is presented. The model consists of linear springs and dashpots and can be solved analytically. Based on the modeling, the curved profile of the peeling tape is spontaneously determined in terms of viscoelastic properties of adhesives. Using this model, two experimental results are discussed: critical peel rates in the p...

Frogs are well-known to capture elusive prey with their protrusible and adhesive tongues. However, the adhesive performance of frog tongues and the mechanism of the contact formation with the prey item remain unknown. Here we measured for the first time adhesive forces and tongue contact areas in living individuals of a horned frog (Ceratophrys sp.) against glass. We found that Ceratophrys sp. ...

Using 10-(2,5-dihydroxyphenyl)-10-hydrogen-9-oxo-10-phosphine-10-oxide (DOPO-H Q), N,N-diethyl-bis(hydroxyethyl) aminomethylene phosphate diethyl (FRC-6), and (6-oxo- 6H-dibenzo[c,e][1,2]oxphosphine-6-yl) hydroxylmethyl-thiophene (DOPO-SF) as reactive flame retardants, the flame-retardant polyurethane pressure sensitive adhesive (FRPU-PSA) were prepared. The fourier transform infrared (FTIR), t...
