Grafting of poly(ethylene oxide)/poly(butylene terephthalate) block copolymers onto hydroxyapatite particles.
Biodegradable HA composite systems based on PEOT/PBT have attracted much attention [1]. Making use of the reactivity of surface hydroxyl groups, PEOT/PBT [2] copolymers have been grafted to HA particles using diisocyanate coupling agents. This resulted in improved mechanical properties of composites. In this study, we set out to covalently bind 1000PEOT70PBT30 to HA by direct surface grafting v...
متن کاملPhase Structure and Properties of Poly(ethylene terephthalate)/High-Density Polyethylene Based on Recycled Materials
Blends based on recycled high density polyethylene (R-HDPE) and recycled poly(ethylene terephthalate) (R-PET) were made through reactive extrusion. The effects of maleated polyethylene (PE-g-MA), triblock copolymer of styrene and ethylene/butylene (SEBS), and 4,40-methylenedi(phenyl isocyanate) (MDI) on blend properties were studied. The 2% PE-g-MA improved the compatibility of R-HDPE and R-PET...
متن کاملSolid phase synthesis of biohybrid block copolymers.
A new versatile route to synthesise biohybrid block copolymers is presented in which an amine terminated polymer is attached to an aldehyde functionalised resin, from which in subsequent steps the desired peptide can be grown using standard procedures.
متن کاملPreparation and characterization of polyethylene/ glass fiber composite membrane prepared via thermally induced phase separation method
Grinded glass fiber (GGF) embedded high density polyethylene (HDPE) membranes were prepared via thermally induced phase separation method. FESEM images showed that all the membranes had leafy structure, indicating a solid-liquid mechanism during phase separation. The results of EDX and TGA analyses confirmed that the fibers were dispersed in the HDPE matrix uniformly. Normalized water flux of t...
متن کاملKinetic theory of microphase separation in block copolymers
A semiphenomenological theory that has the advantage of taking into account nonlinear and nonlocal contributions in the free energy for microphase separation of block copolymers is proposed. A kinetic nonlinear equation defining the process of structure formation from a melt is obtained, and its analytical solution at the melt-structure transition temperature is examined. In this region, the st...
