The results from x - ray diffraction demonstrated that pp / mmtome was a fully intercalated nanocomposite , pp / mmtom and pp / ommt were partly intercalated nanocomposites , but the intercalation effect of pp / mmtom nanocomposite was better ; the crystallization characteristics of pure pp and pp / mmt nanocomposites were investigated by dsc , waxd and pom . the result of these testing showed that mmt nano - layers acted as nucleating agents for the crystallization of pp , the addition of mmt had effect on the crystallization process , leading the increasing of crystallization temperature crystallization rate and crystallinity , but also the dimension of spherulite reduced . but the formation of pp crystal did n ' t change , the formation of pp crystal in three pp / mmt nanocomposites and pure pp were a - form on the whole ; influences of three sorts of mmt on mechanical properties of pp / mmt nanocomposites were studied , as a result , the addition of mmt comprehensively improved mechanical properties of pp : notched impact strength , tensile strength and flexural properties were all increasing , but the extent of increasing were n ' t large 通過xrd分析比較這三種pp mmt納米復合材料微觀結構得到， pp mmt _ ( ome )屬于完全插層， pp mmt _ ( om )與pp ommt的插層程度相近，但是pp mmt _ ( om )相對較好；通過對純pp和三種pp mmt納米復合材料的結晶性能研究發現，蒙脫土納米片層對pp結晶產生明顯的異相成核作用，結晶能力增強，使pp的結晶溫度和結晶速率提高，結晶度增加，球晶晶粒細化，但是沒有改變pp的結晶形態，三種pp mmt納米復合材料的結晶形態都屬于晶；通過對pp mmt納米復合材料的力學性能測試得知，蒙脫土的加入全面提高了pp的力學性能，缺口沖擊強度、拉伸強度和彎曲性能都有一定程度的提高，浙江{ _業大學碩十學位論文摘要但是提高幅度都不是很大，不過ommt 、 mmtom和mmtc ) me三種蒙脫土對pp力學性能有著不同的改性作用，其中pp / mmtom最好， pp月邊mto崛次之， pp / ommt最低，這種情況主要是由蒙脫土對pp結晶性能的影響和蒙脫土的納米改性作用造成的。
The polymerization kinetics of pam , the feeding pattern of the initiator naoh and a method used to characterize the spherulite morphology of monomer casting nylon were investigated . the mechanics of inhibition of pam to the polymerization of nylon was certificated by means of a series of experiments 通過兩個體系的pam pa - 6復合材料的力學性能、 sem 、 xrd 、 dsc和tem等測試方法研究復合材料的結構與性能間關系，表明聚甲亞胺端基對復合材料性能有一定的影響。
The analysis of ir spectrum and melt flow index showed that the composite had a micro - crosslinking structure , and the analysis of dsc discovered there was - spherulite in the aggregate structure of the composite of pp 紅外光譜分析和熔體質量流動速率的測定表明，復合材料體系產生了微交聯； dsc分析發現， pp材料的聚集態結構中含有球晶。
The results of linear regression indicate that the addition of pam do not alter the avrami exponents , about 2 - 3 , which suggests that the crystallization modes might be a mixture of three - dimensional spherulite and two - dimensional circular Avrami方程線性回歸結果表明聚甲亞胺的加入對體系的avrami指數n影響不大， n值約在2 3之間。
A reasonable mechanism of the concentric ring like patterns on the surface of phbv spherulite was given first . the segregation of hv content between cystal and amorphous parts was observed and the phenomena caused were discussed 首次對phbv球晶表面觀察到的同心圓環條紋的成因作了合理解釋，揭開了這一現象形成的本質。
On the surface of phbv spherulite , some concentric ring like patterns will occur . based on the procedure of the formation of ring - like patterns , the possible mechanism is given 在球晶的表面出現有同心圓環狀條紋，經實驗驗證為表面的不平整所導致，形成機理主要可能是結晶過程中的體積收縮。
And the spherulite growth rate of phbv is studied and the factors , which influence the growth rate and the formula of spherulite growth rate , were discussed 并通過對phbv球晶生長速率的測定，對結。晶生長的速度方程及影響因素做出修正。
