To enhance the mechanical strength and bioactivity of poly(lactic acid) (PLA) to the level that can be used as a material for spinal implants, poly(glycolic acid) (PGA) fibers and hydroxyapatite (HA) were introduced as fillers to PLA composites. To improve the poor interface between HA and PLA, HA was grafted by PLA to form HA-g-PLA through coupling reactions, and mixed with PLA. The size of the HA particles in the PLA matrix was observed to be reduced from several micrometers to sub-micrometer by grafting PLA onto HA. The tensile and flexural strength of PLA/HA-g-PLA composites were increased compared with those of PLA/HA, apparently due to the better dispersion of HA and stronger interfacial adhesion between the HA and PLA matrix. We also examined the effects of the length and frequency of grafted PLA chains on the tensile strength of the composites. By the addition of unidirectionally aligned PGA fibers, the flexural strength of the composites was greatly improved to a level comparable with human compact bone. In the bioactivity tests, the growth of apatite on the surface was fastest and most uniform in the PLA/PGA fiber/HA-g-PLA composite.

Novel composite resins with dual absorption properties of water and oil are prepared by the polymerization of high internal phase emulsion (HIPEs) with n-butyl methacrylate as the external phase monomer and acrylamide as the internal phase monomer. The subsequent polymerization leads to the formation of water and oil dual-absorption composite resins. The morphology of porous structure and microcosmic phase separation after water/oil uptake is observed by scanning electron microscopy (SEM). The water and oil absorbency strongly depend on composition. The composites with saturated water uptake could absorb the chloroform again but cant absorb water if saturated with chloroform first. And the resins exhibit great reusability, keeping almost constant absorbency. The present methodology could be a potential approach to obtain amphiphilic composites, which possess potential applications in the bioengineering, medical and industrial fields.
