Immobilization of phospholipase D on macroporous SiO/cationic polymer nano-composited support for the highly efficient synthesis of phosphatidylserine.

Novel nano-composites were prepared by coating epoxy resin-based cationic polymer in nano-thickness via in-situ curing on the nano-wall of macroporous SiO with pore size of 0.5∼1 μm. By changing the thickness of polymer coating the specific surface area and porosity varied in range of 115∼74 m/g and 90.

Efficient immobilization of phospholipase D on novel polymer supports with hierarchical pore structures.

In this article, novel epoxy resin-based hierarchical porous polymers (HPSs) have been prepared through a non-sol-gel and template-free approach using crystalline trimethylolpropane (TMP) as porogen. The polymers exhibit dimensional stability and possess 3-dimentional interconnected multi-scale pores. In range of 50 μm~10 nm are ultra-macro-pore in between skeleton, macro-pore on skeleton and meso-pore in network, respectively.
