Exploring the Influence of Shell Feeding Method on the Properties ofStyrene/Acylate Latex Interpenetrating Polymer Network with Core-ShellStructure

Styrene/acrylate LIPNs with core-shell structure were synthesized through three different shellfeedingmethods, which included direct monomer, pre-emulsion and pre-swelling feeding. Thestability, particle size and mechanical properties of the samples were investigated using zeta potential,DLS and mechanical analysis. Experimental results demonstrated that the pre-swelling methodproduced samples with the smallest particle size, specifically with a diameter of ۱۱۱ nm, and thegreatest stability, characterized by a zeta potential of -۱۲.۶۱ mV.
