Nanoarchitectonics Based on Ultrasonication-Assisted Polymerization for Enhanced Interaction Between Liquid Monomer and LDH Nanosheets

Enhancing Metallocene Catalyst Activity: Utilizing Layered Double Hydroxide for Ethylene–Propylene Copolymerization

“…Our recently published paper reports similar observations for ZnAl LDHs. [ 28 ] All the other LDHs (ZnAl, MgAl, NiAl, and MgFe) interrelating DDS anion demonstrated 003 peak around 2 θ = 3.2°, thereby corresponding to a basal spacing in the range of 2.6–2.8 nm ( Table 1 ). Similar observations have been reported in the literature.…”

“…In recent years, LDHs have garnered substantial research interest for various applications such as energy storage, [ 23 ] drug delivery, [ 24 ] catalysis, [ 25 ] and polymer composites. [ 26–29 ] Freshly prepared LDHs contain an abundance of free water molecules and surface hydroxyl groups, which can be controlled by using solvents and heat treatment.…”

“…For instance, the innovative ultrasonication‐assisted synthesis of ethylene–propylene‐1‐hexene‐ZnAl‐LDH nanocomposites, in which ultrasonication played a critical role in LDH exfoliation, resulted in enhanced catalytic activities and thermomechanical properties. [ 28 ] Moreover, studies on the in situ synthesis and thermal degradation of EP copolymers and ethylene–propylene‐1‐hexene terpolymers have demonstrated the effect of 1‐hexene dosage on product yield and thermal stability. [ 27 ] Similarly, we reported that the incorporation of NiFe‐ (anion) LDHs into EP copolymers improved thermal stability and influenced the microstructure of the resultant polymers.…”

“…However, the treatment of LDHs with surfactants, such as sodium dodecyl sulfate (SDS), intercalates, and dodecyl sulfate (DDS) anions, via ion exchange in the galleries of the layered material, resulting in an enlarged basal spacing. [ 28 ] LDH‐DDS can be delaminated into a single sheet in a toluene solvent. [ 32–34 ] This property could be advantageous in supported catalyst synthesis and polymerization if toluene is used as the reaction solvent.…”
