Interaction forces measured between poly(N-isopropylacrylamide) grafted surface and hydrophobic particle

Choline phosphate functionalized cellulose membrane: A potential hemostatic dressing based on a unique bioadhesion mechanism

“…When pulling off, a much stronger adhesive force was observed (F adhesive = 1.1 ± 0.2 nN). This is attributed to the short-range adhesive force caused by a strong hydrophobic interaction and is typical for interaction between the Si 3 N 4 tip and a hydrophobic surface [36,37]. After grafting the polymer, the approach curve of CM-N 3 exhibits a repulsive force instead of a JTC.…”

Preparation and characterization of thermosensitive polymers grafted onto silica-coated iron oxide nanoparticles

“…The character- istics of PNIPAM have been analyzed and reported extensively in previous studies [10,11]. It presents a coil-to-globule transition in aqueous solution when temperature is raised above the lower critical solution temperature (LCST) at around 32 • C. The phenomenon of PNIPAM at LSCT is caused by the reversible hydration and dehydration between amine groups and solutions [12]. The phase transition behavior can be affected by the chemical nature and molar concentration of the co-monomer, since it is possible to affect the balance of the enthalpy and entropy of mixing polymers with solvents [13].…”

Preparation of Thermosensitive Hollow Imprinted Microspheres via Combining Distillation Precipitation Polymerization and Thiol‐ene Click Chemistry

“…The phenomenon ℃ of PNIPAM at LSCT is caused by the reversible hydration and dehydration between amine groups and solutions. [17] The phase transition behavior can be affected by the chemical nature and molar concentration of the co-monomer, since it is possible to affect the balance of the enthalpy and entropy between polymers and solvents. [18] So far, most thermosensitive copolymers are used as controlled release carriers in drug delivery systems.…”
