Characterization of styrene- co -butyl acrylate/Cloisite Na + nanocomposite film synthesized via soap free emulsion polymerization

Preparation and characterization of a new bio nanocomposites based poly(glycerol sebacic‐urethane) containing nano‐clay (Cloisite Na+) and its potential application for tissue engineering

“…A decrease in ε b was utterly consistent with the increase in Young's modulus and calculated cross‐linking density values. Previous studies reported in literature have also shown that the addition of Cloisite Na + had a similar effect on E and ε b of SBR, NR, 45 and styrene‐co‐butyl acrylate nanocomposites 46 …”

“…44 Na + had a similar effect on E and ε b of SBR, NR, 45 and styrene-cobutyl acrylate nanocomposites. 46 The elasticity of the PGSU-based bioelastomers was further studied by cyclic tensile testing. The elastomeric films were undergone to 20% cyclic tensile strain for 10 continuous cycles, and the loading and unloading stress-strain curve was recorded (Figure 4G).…”

“…Furthermore, absorbed water molecules probably interfere with and weaken the hydrogen bonds between the hydroxyl groups of the clay As a result, water molecules can form new hydrogen bonding with the hydroxyl groups of Cloisite Na + platelets, making water uptaking much easier. 46,59 The biodegradation rate of TE scaffolds designed as temporary implants strongly determines their application range and targeted tissue. Figure 7C,D shows the in-vitro degradation of the PGSU-based bioelastomers determined in two different degradation media (PBS and PBS + Enzyme solutions, 37 C) for 30 days.…”

Effect of Bifunctional Montmorillonite on the Thermal and Tribological Properties of Polystyrene/Montmorillonite Nanocomposites

“…However, the relatively weak thermal stability and heat resistance of PS has become a significant challenge, hindering its further applications in a variety of areas. To compensate this demerit, the addition of inorganic clay to the PS matrix can be further helpful to enhance the properties of the PS matrix [17]. Recently, an attractive technique to synthesize the clay-polymer nanocomposite is the emulsion polymerization due to the great advantage of controlled morphology and employment of water as a dispersion medium [18].…”
