通过xrd分析比较这三种pp mmt纳米复合材料微观结构得到， pp mmt _ ( ome )属于完全插层， pp mmt _ ( om )与pp ommt的插层程度相近，但是pp mmt _ ( om )相对较好；通过对纯pp和三种pp mmt纳米复合材料的结晶性能研究发现，蒙脱土纳米片层对pp结晶产生明显的异相成核作用，结晶能力增强，使pp的结晶温度和结晶速率提高，结晶度增加，球晶晶粒细化，但是没有改变pp的结晶形态，三种pp mmt纳米复合材料的结晶形态都属于晶；通过对pp mmt纳米复合材料的力学性能测试得知，蒙脱土的加入全面提高了pp的力学性能，缺口冲击强度、拉伸强度和弯曲性能都有一定程度的提高，浙江{ _业大学硕十学位论文摘要但是提高幅度都不是很大，不过ommt 、 mmtom和mmtc ) me三种蒙脱土对pp力学性能有着不同的改性作用，其中pp / mmtom最好， pp月边mto崛次之， pp / ommt最低，这种情况主要是由蒙脱土对pp结晶性能的影响和蒙脱土的纳米改性作用造成的。 | | 4. | The wxrd characterization showed that o - mmt possessed obvious nucleation effect on the crystallization process of b - pp . jeziorny and mo methods were used to study the non - isothermal crystallization process . the obtained value of kinetics parameters such as tp , n , zc , t1 / 2 , a h , f ( t ) , e showed that the o - mmt has nucleation effect in crystallization of pp and can increases the crystallization temperature of pp , quickens the crystall ization velocity , decreases the crystallization activation energy of pp but decreases the crystallization degree of pp at the same time
运用jeziorny法和mo法研究了聚丙烯和复合材料的非等温结晶过程，所得到的非等温结晶过程动力学参数t _ p ， n ， z _ c ， t _ ( 1 / 2 ) ， h ， f ( t ) ， e的数值表明，有机蒙脱土的加入可以起到异相成核的作用，从而提高pp的结晶温度，加快pp的结晶速率，降低pp的结晶活化能，但同时也会降低pp的结晶度。 | | 5. | Blend in molten state make hdpe crystals small , crystallinity large , quantity of cb particle benefit to conductivity decreasing ; in solid state cb aggregate is sheltered with a insulate hdpe film , also cb structure will be broken down during blend ; all of these will make conductivity bad . but processing alds can lower this effect obviously . 3 . the effect of crosslink is restricting the movement of molten polymer molecules
为此笔者认为固相混合使hdpe晶粒尺寸变小，结晶度增大，使得异相成核的晶粒增多，参与导电的炭黑粒子数量减少：熔混却使炭黑粒子表面被覆一层绝缘膜：这都将导致材料的导电性明显变差，同时两种混合还会造成炭黑结构的破坏，皆使得材料的导电性明显变差。 |
