The　Avrami　equation　modified　by　Jeziorny,　the　Ozawa　model　and　the　Mo　equation　combining　the　Avrami　and　Ozawa　theories　were　employed　to　describe　the　non-isothermal　crystallization　kinetics　of　poly(vinylidene　fluoride)　(PVDF),　and　PVDF/microcrystalline　graphite　(MCG)　composites.　It　was　found　that　the　Ozawa　model　failed　to　describe　the　non-isothermal　crystallization　process　for　PVDF　and　its　composites,　while　Mo＇s　theory　provided　good　fitting　for　neat　PVDF　but　did　not　describe　the　non-isothermal　crystallization　well　for　the　PVDF/MCG　composites.　The　addition　of　MCG　promoted　the　crystallization　rate　of　PVDF,　which　indicates　that　MCG　acted　as　a　nucleating　agent.　The　absolute　values　of　the　effective　activation　energy　of　the　PVDF/MCG　composites　calculated　by　the　Kissinger　equation,　were　higher　than　that　of　neat　PVDF,　confirming　that　MCG　acted　as　a　nucleating　agent　and　promoted　the　crystallization　rate　of　PVDF.
