Fluorescent bracelet-like Cu@cross-linked poly(vinyl alcohol) (PVA) microrings by a hydrothermal process†
Abstract
Novel bracelet-like Cu@cross-linked poly(vinyl alcohol) (PVA) microrings have been prepared through a PVA-assisted hydrothermal process. Bracelet-like microrings are composed of inner copper nanorings and outer cross-linked PVA beads. The formation of bracelet-like microrings consists of two steps, i.e. the growth and self-coiling of PVA-wrapped copper
