Special Issue Information

Dear Colleagues,

Well-defined amphiphilic polymers consisting of hydrophilic ("water-loving") and hydrophobic ("water-hating") components are at the forefront of smart material research due to their high complexity in structure design, excellent control in molecular self-assembly, and versatile functionality in material engineering and medical sciences. With the recent advances in controlled/living radical polymerization methods, combined with various coupling techniques, a large array of new functional amphiphilic polymers having various architectures such as block, grafted, cyclic, star-shape, dendritic, comb-like and hyperbanched have been developed, and their smart self-assemblies, ranging from colloidal systems, including structured Janus nanoparticles, micelles, vesicles, hydrogels and phase-transit materials, to engineered surface patterns have been unveiled. More importantly, these sophisticated materials show high performance in various applications, such as in advanced delivery carriers, tissue engineering, template-directed colloidal self-assembly, surface modification, and many other applications throughout industry. This Special Issue aims to provide a platform for the scientific community to share their latest developments and discoveries in the synthetic strategies, mechanism underlying smart self-assemblies, and the emerging applications of functional amphiphilic polymers in different fields.

Abstract
In this work we prepared poly(styrene–b–vinylphenol) (PS-b-PVPh) by sequential anionic living polymerization and poly(ethylene oxide-b-4-vinylpyridine) (PEO-b-P4VP) by reversible addition fragmentation chain transfer polymerization (RAFT) by using poly(ethylene oxide) 4-cyano-4-(phenylcarbonothioylthio)pentanoate (PEO-SC(S)Ph) as a macroinitiator with two

In this work we prepared poly(styrene–b–vinylphenol) (PS-b-PVPh) by sequential anionic living polymerization and poly(ethylene oxide-b-4-vinylpyridine) (PEO-b-P4VP) by reversible addition fragmentation chain transfer polymerization (RAFT) by using poly(ethylene oxide) 4-cyano-4-(phenylcarbonothioylthio)pentanoate (PEO-SC(S)Ph) as a macroinitiator with two hydrogen bonded acceptor groups. When blending with disordered PEO-b-P4VP diblock copolymer, we found the order-order self-assembled structure transition from lamellar structure for pure PS-b-PVPh to cylindrical, worm-like, and finally to PEO crystalline lamellar structures. Taking the advantage of the ΔK effect from competitive hydrogen bonding strengths between PVPh/P4VP and PVPh/PEO domains, it could form the hierarchical self-assembled morphologies such as core–shell cylindrical nanostructure.

Copoly(phthalazinone biphenyl ether sulfone) (PPBES) as a commercially available polyarylether is a promising orthopaedic implant material because its mechanical properties are similar to bone. However, the bioinert surface of polyarylether causes some clinical problems after implantation, which limits its application as an implant material. In this study, the surface of PPBES was modified by a biomineralization method of polydopamine-assisted hydroxyapatite formation (pHAF) to enhance its cytocompatibility. Polydopamine (PDA) coating, inspired by the adhesion mechanism of mussels, can readily endow PPBES with high hydrophilicity and the ability to integrate via the bone-like apatite coating. PPBES and PDA-coated PPBES were evaluated by scanning electronic microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and contact angle measurement. The water contact angles were reduced significantly after coating with PDA. PDA was successfully synthesized on PPBES and more PDA was obtained by increasing the temperature. Bone-like apatite on PPBES (apatite-coated PPBES) was confirmed by SEM and transmission electron microscopy (TEM). The cytotoxicity of pristine PPBES and apatite-coated PPBES were characterized by culturing of NIH-3T3 cells. Bone-like apatite synthesized by pHAF could further enhance cytocompatibility in vitro. This study provides a promising alternative for biofunctionalized PPBES with improved cytocompatibility for bone implant application. Full article

Amphiphilic hybrid POSS copolymer: Mechanism in Self-Assembly and Applications

Hong Chi

Polyhedral oligomericsilsesquioxane (POSS) is a kind of hybrid molecule with strong hydrophobicity, good strength and modulus, high abrasive and oxidation resistance and good biocompatibility. Due to its unique nanocage-like architecture and properties, POSS has received tremendous attention in amphiphilic hybrid copolymer assemblies and many interesting studies ranging from academic research to practical applications such as nano-medicines, fluorescent labeling, stimuli-responsive macromolecules, and controllable release etc. This contents of this review will be organized to encompass new ideas and research work carried out over the last several years on POSS based amphiphilic copolymer and their synthesis, mechanism in self-assembly. Finally their potential applications in various fields will be discussed.
