Preparation of graphene/PMMA composites with assistance of ultrasonic wave under supercritical CO2 conditions

Abstract

Highlights Ultrasound can initiate polymerization above the threshold. Ultrasonic time for ultrasonic initiation polymerization also has an optimal value. Ultrasound-induced methdod is better than in-situ polymerization.

Ultrasonics and sonochemistry: Editors’ perspective

“…An US-assisted mechano-chemical cracking method has been proposed to produce graphene oxide (GO) [161] . In this study, Miscanthus, an energy crop, was first used as a carbon precursor, pyrolysed at 1200 °C and then subjected to edge-carboxylation via ball-milling in a CO 2 -induced environment.…”

Effect of ultrasound power on HCl leaching kinetics of impurity removal of aphanitic graphite

“…In addition, it is important to note that the ultrasound-assisted synthesis, exfoliation, and functionalization of graphene derivatives using high-grade graphite have been systematically investigated [ [51] , [52] , [53] , [54] , [55] , [56] ]. Li, et al [ 57 ] calculated the selection and breakage functions of ultrasound-assisted exfoliation and breakage process of graphite oxide.…”

Preparation of Glass Fiber/Poly(Ether Ether Ketone) Composite Foam with Improved Compressive Strength and Heat Resistance

“…At present, polymer foams are mainly prepared from common plastics such as polymethyl methacrylate (PMMA), [25][26][27] polystyrene (PS), [28][29][30] polypropylene (PP), [31][32][33] and polyethylene (PE). [34,35] However, as a result of the increasing range of applications of these polymer foams, especially those involving extreme environments, the development of highperformance foams is urgently required.…”
