The characteristic and deficiency of polyhydroxyalkanoates(PHA) were introduced. The progress on PHA modification by blending with natural polymers,artificially synthesized polymers and nanoparticles were summarized respectively, for example starch,cellulose acetate butyrate (CAB),poly(caprolactone)(PCL),poly(propylenecarbonate)(PPC),organophilic montmorillonite(OMMT),carbon nanotubes(CNT) and so on. The compatibility,crystallization,mechanical properties and thermostability of different PHA blends were reviewed. The development trend of modified PHA was prospected.
