Collagen mimetic polypeptides (CMPs) pendanted with linear or dendritic oligoethylene glycols (OEG) via ether linkage were synthesized, and their thermoresponsiveness, secondary structures and supramolecular assembly investigated. High molar masses of OEGylated CMPs were achieved by polyamidation of tripeptide precursors through activated ester strategy. Pendanted linear OEGs confer CMP with enhanced...
The star-shaped amphiphilic inorganic–organic hybrid polymer POSS-(PEO) 8 prepared via click chemistry can self-assemble into spherical aggregates by directly dissolving the hybrid polymer in water. The regular spherical aggregates were gradually transformed to deformed spherical aggregates, cylinders and sheets through adding different amount of α-CD molecules into the POSS-(PEO) 8 ...
A series of bio-based self-healing polymers was prepared by cross-linking a furan polymer, poly(2,5-furandimethylene succinate), with bis-maleimide compounds by means of Diels–Alder reactions. In addition to the amount of the bis-maleimide linker, the molecular structure of the bis-maleimide played a key role in determining the extent of the Diels–Alder reaction and the mechanical and healing properties...
Novel amphiphilic ethyl cellulose (EC) brush polymers with mono and dual side chains of poly(2-(2-methoxyethoxy)ethyl methacrylate)-co-oligo(ethylene glycol) methacrylate) (P(MEO 2 MA-co-OEGMA)) and poly(2-(N,N-dimethylamino)ethyl methacrylate) (PDMAEMA) were synthesized by the combination of atom transfer radical polymerization (ATRP) and click chemistry. The molar ratio of P(MEO 2 ...
Novel amphiphilic chitosan-g-poly(ε-caprolactone)-(g-poly(2-(2-methoxyethoxy)ethyl methacrylate)-co-oligo(ethylene glycol) methacrylate) (CS-g-PCL(-g-P(MEO 2 MA-co-OEGMA))) copolymers with double side chains of PCL and P(MEO 2 MA-co-OEGMA) were synthesized via combination of ring-opening polymerization (ROP), atom transfer radical polymerization (ATRP) and click chemistry. The molar...
Biodegradable star-shaped poly(ɛ-caprolactone) and poly(ɛ-caprolactone-b-l-lactide) (5sPCL-b-PLLA) with five arms were synthesized by ring-opening polymerization (ROP) from an asymmetric BIS-TRIS core via “core-first” strategy. Subsequently, a series of amphiphilic and double responsive star-block copolymers were synthesized by Z-RAFT star polymerization of N,N-dimethylamino-2-ethyl methacrylate (DMAEMA)...
