摘要

This work investigates the reinforcing effects of ionic liquid monomer

linear and branched poly(ionic liquids) on poly(vinyl chloride) (PVC). Linear poly(ionic liquids) exhibit the best strength and toughness

which are significantly superior to dioctyl phthalate (DOP).

Abstract

This study simultaneously plasticizes and strengthens poly(vinyl chloride) (PVC) with structurally different ionic liquids (ILs)

namely monomeric [Bmim

]

NTf

linear polymerized PImC

NTf

and branched polymerized P(VIm-4)NTf

. Notably

PImC

NTf

exhibits the best performance. Dynamic mechanical analysis reveals that the glass transition temperature of PImC

NTf

/PVC composite film is lower than that of dioctyl phthalate (DOP)/PVC

indicating enhanced processability. Compared with neat PVC film

the 4% PImC

NTf

/PVC film exhibits 747.2%

165.4%

and 49.1% increases in elongation at break

tensile strength

and Young’s modulus

resp

ectively

along with a 27.4-fold rise in fracture energy. Additionally

the thermal stability

hydrophobicity

and wear resistance of PVC are also improved. These findings demonstrate the great potential of linear polymerized ILs as innovative PVC plasticizers.
