The integration mode and release modulation of growth factors inside the scaffolds represent major challenges for inductive tissue regeneration. The integration of the bioaffinity of heparin with growth factors and the biomimicry of electrospun fibrous network to extracellular matrices is expected to efficiently bind and gradually release growth factors. Functional ketone groups were incorporated...
The compatibility of surface properties and the degree of interfacial action between filler and base directly affect the structure of their composites and make great contribution to a series of properties of composite materials. Interactions among rectorite (REC), quaternary ammonium salt and polymer are investigated via molecular simulation. Inverse gas chromatography (IGC) has been used to investigate...
Five series of binary copolymers, poly[2,5-di(ROOC)styrene-co-2,5-di(R′OOC)styrene]s (R=n-C 3 H 7 –, R′=C 2 H 5 –, n-C 4 H 9 –, and n-C 5 H 11 –; R=n-C 6 H 13 –, R′=n-C 4 H 9 –, and n-C 5 H 11 –), were synthesized via free radical polymerization. The random nature of the copolymers was expected...
Crystallization and melting of a poly(ethylene oxide) (PEO) diblock copolymer containing a tablet-like block of poly{2,5-bis[(4-methoxyphenyl)oxycarbonyl]styrene} (PMPCS) in ultrathin films have been studied using atomic force microscopy (AFM) coupled with a hot stage. The PEO and PMPCS block possess the number-average molecular weights (M n ) of 5300 and 2100g/mol, respectively. The ultrathin...
A poly(ethylene oxide) diblock copolymer containing a short block of poly{2,5-bis[(4-methoxyphenyl)oxycarbonyl]styrene} (PEO-b-PMPCS) has been successfully synthesized via atom transfer radical polymerization (ATRP) method. The number average molecular weights (M n ) of the PEO and PMPCS blocks are 5300 and 2100g/mol, respectively. Combining the techniques of differential scanning calorimetry...
