▎ 摘  要

NOVELTY - Synthesizing pH stimulus responsive star-shaped graphene dispersant comprises (i) adopting electron transfer regeneration catalyst atom transfer radical polymerization (ARGET-ATRP) method, using ethyl alpha -bromoisobutyrate as an initiator to initiate polymerization of styrene to obtain a first macroinitiator, and marking as PS-Br, (ii) using electron transfer regeneration catalyst atom transfer radical polymerization (ARGET-ATRP) method, polymerizing dimethylaminoethyl methacrylate using ethyl alpha -bromoisobutyrate as an initiator to obtain a second macroinitiator, and marking as PDMAEMA-Br, and (iii) using the first arm after the nuclear method synthesis, using the macro-initiators PS-Br and PDMAEMA-Br in the steps (i) and (ii), taking divinylbenzene (DVB) as core, and synthesizing star-shaped polymer. USE - The method is useful for synthesizing pH stimulus responsive star-shaped graphene dispersant. ADVANTAGE - The dispersant has good dispersion performance and storage stability.
