“…The new strategy consists in replacing the classical amphiphilic template by an induced and reversible assembly of watersoluble block copolymers (WSBC) [13][14][15], which allows to recover the template in aqueous solution. The micellization [16][17][18] process results from electrostatic interactions between two oppositely charged polymers in aqueous solution, a hydrophilic polyelectrolyte-neutral diblock copolymer and a homopolyelectrolyte.…”

“…Double hydrophilic block copolymers (DHBCs) are water-soluble macromolecular compounds which consist of two water-soluble blocks of different chemical nature [1]. Poly(ethylene oxide) (PEO) and poly(2-hydroxyethyl methacrylate) (PHEMA) are two of the most frequently investigated classes of hydrophilic polymers.…”

“…1 H NMR study in CDCl 3 indicated that the hydroxyl end group of the PEO was fully esterified (data not shown). HEMA was polymerized in methanol using PEO-Br as the macroinitiator, CuBr/ bpy as the catalyst and ligand.…”

“…The self-assemble behaviors of DHBCs in water have attracted much interest recently due to its two water-soluble blocks [19]. A recent overview on the synthetic routes toward DHBCs and some of their prominent applications was presented by Colfen [1]. Armes [20] found that copolymerizations of HEMA with other comonomers allowed the cloud point behavior to be manipulated.…”

“…IR, 1 H NMR, and GPC analysis indicate that PEO-b-PHEMA block copolymer with low polydispersity index (M w /M n ≈ 1.1) has been formed. Selfassembly of this double hydrophilic block copolymer in the selective solvent and water was also studied.…”

Synthesis and self-assembly of poly(ethylene oxide)-b-poly (2-hydroxyethyl methacrylate)

Poly(ethylene oxide)-b-poly(2-hydroxyethyl methacrylate) (PEO-b-PHEMA) was synthesized by successive atom transfer radical polymerization (ATRP) of 2-hydroxyethyl methacrylate（HEMA） monomer using PEO-Br macroinitiator as initiator, CuBr/CuBr 2 and 2,2"-bipyridyl (bpy) as catalyst and ligand. IR, 1 H NMR, and GPC analysis indicate that PEO-b-PHEMA block copolymer with low polydispersity index (M w /M n ≈ 1.1) has been formed. Selfassembly of this double hydrophilic block copolymer in the selective solvent and water was also studied. Owing to the high hydrophilic nature of the PEO and PHEMA blocks, this double hydrophilic block copolymer cannot disperse well in water. So block copolymer was modified by part esterification of PEO-b-PHEMA with acetic anhydride, which increased the hydrophobic group of the PHEMA block. The TEM results show that this block copolymer spontaneously form well-defined micelles in water.

This article focuses on biomineralization processing involving nanoparticle self‐assembly. Biomineralization is a process of depositing inorganic or inorganic–organic hybrid materials as complex shapes or as hierarchical structures on various size scales having unique properties. Emerging nonclassical crystallization methods of self‐assembly are summarized, including oriented attachment, mesocrystal growth from amorphous precursors, and polymer particle assembly from polymer‐induced liquid precursors. Recent progress in understanding biomineralization in nature and biomimetic mineralization via nanoparticle self‐assembly directed by organic molecules is summarized. Crystallization in organisms commonly involves biopolymer‐induced nucleation and growth, self‐assembly of nanobuilding blocks, and organization of amorphous precursors. A better understanding of biomineralization in organisms and self‐assembly process, in general, will lead to the rational design and synthesis of functional materials having well‐defined hierarchical structures, controlled length scales, and desired properties under environment‐friendly conditions.
