Adhesion performance and surface characteristics of low surface energy psas fluorinated by UV polymerization

Abstract

Acrylic pressure sensitive adhesives (PSAs) have a range of applications in industry, such as medical products, aircraft, space shuttles, electrical devices, optical products, and automobiles, etc. In this study, acrylic PSAs with fluorinated groups were synthesized using 2,2,2-trifluoroethyl methacrylate (TFMA) under UV radiation. The surface properties and adhesion strength were measured. The results showed that the addition of TFMA reduced the surface energy of the PSAs and improved the adhesion strength.

Biological protein‐resistance layer construction of recombinant hirudin on polymethyl methacrylate IOL surface

“…The experiment of wettability and surface energy about the modification of PMMA IOL with different level showed no certain regulations. Some researchers pointed out that the data of the surface energy could affect the performance of surface protein or cell adhesion, and lower surface energy may be more effective for resistance to the adhesion . However, it was not the only factor that surface energy could affect the protein adsorption .…”

“…Some researchers pointed out that the data of the surface energy could affect the performance of surface protein or cell adhesion, and lower surface energy may be more effective for resistance to the adhesion. 15,16 However, it was not the only factor that surface energy could affect the protein adsorption. 17 The generation of acylamino HNAC@O could be caused by the reaction between the carboxyl groups ACOOH of rH molecule and the amino groups of plasma, so the combination was more stable.…”

Antibacterial surfaces obtained through dopamine and fluorination functionalizations

“…After reaction of the SS-PDA surface with pentadecafluorooctanoyl chloride, additional peaks associated with the F2s (E b ∼ 36 eV), F1s (E b ∼ 689 eV) and F KLL Auger (main peak at ∼869 eV) signals, respectively, appear in the survey spectrum of SS-PDA-F15 surfaces (Fig. 1C) [29,30]. This result indicates successful reaction of pentadecafluorooctanoyl chloride with functional groups localized on surface.…”

“…4(B)) can be decomposed into five peaks. In addition to the three peaks at 285, 287 and 289 eV corresponding to CH, C-O/C-N and C O of polydopamine and PET undercoat, two additional peaks appears at 292 and 294 eV corresponding to CF 2 and CF 3 groups, respectively [29,30]. The F1s core-level spectrum of the PET-PDA-F15 surfaces (Fig.…”

Why hot melts do not stick to cold surfaces

“…Due to the complexity of the problem, adhesion characteristics are not well predicted in practical situations . Since studies of adhesion are typically performed under isothermal conditions , results are mostly inapplicable to non‐isothermal adhesion.…”
