It was found that in the case of non - isothermal crystallization , the onset and maximum crystallization temperatures of the nylon 6 of the nanocomposites are increased , while the crystallinity and crystallization growth rate is reduced 在非等温条件下，尼龙6石墨纳米薄片复合体系的结晶起始温度以及最大结晶速率时的温度均比纯尼龙6有明显的提高，但结晶度以及结晶速率却出现下降。
Wear mass loss of pa6 composites increases with the increasing of load . the matrix has optimal contents of fillers more or less nano - al2o3 cannot effectively link the molecular chain of pa6 matrix and reinforce pa6 ' s resistance to adhesive and abrading transfer wear ‘业人学硕十学位论文摘要佳填充量，在试验配方中，当纳米a120 :填充量为10phr时，尼龙6的磨损量最低，耐磨性最好。
The variation of friction coefficients of pa6 composites with loading also accords with the friction behaviors of elastic materials under lower load ( p < 100 n ) ; for cu counterface , the friction coefficients of pa6 composites increase with the increasing of filler contents at the same load 我们认为，聚合物材料的摩擦系数变化除了与材料本身性能有关外，还与摩擦副的硬度有关。纳米al _ 2o _ 3的加入，尼龙6的磨损量下降，但是对于尼龙6而言，存在一个最浙江
The pa6 / nano - al2o3 composite is prepared by the extrusion and injection moulding process . besides , the processing method and mechanical properties , the friction and wear characteristic of pa6 / nano - al2o3 composites by annealing were studied . for the al2o3 filler nano - composites are compared with micron - composites , and pa6 composites filled with surface treated nano - al2o3 are compared with pa6 composites filled with untreated nano - al2o3 in mechanical , friction or wear characteristics 采用挤出?注射成型工艺，选择平均粒径约为90nm的有机化处理后的纳米al _ 2o _ 3粒子、未有机化处理的纳米al _ 2o _ 3粒子以及平均粒径为2 - 5 mal _ 2o _ 3粒子作为尼龙6的填充改性粒子，经双螺杆挤出机共混造粒，注塑制样而成。
A novel technique - pan - milling mixing was developed to prepare high performance polymer blends and composites and to control the microstructure by applying the excellent pulverizing , mixing and in - situ compatibilizing functions of our self - designed pan type milling equipment . the pulverizing process and its mechanism of polymers in pan - mill were systematically investigated . through this method , a polypropylene / polyamide 6 ( pp / pa6 ) blend was obtained 本文利用自制的专利设备磨盘形力化学反应器的强大粉碎、混合功能及就地增容作用，建立了用于高性能尼龙6共混复合材料制备及其微相结构控制的“磨盘碾磨混合” ( pan - millingmixing )新方法。
Isothermal and non - isothermal crystallization behaviors were also investigated . the results of ft - ir , uv spectrum , waxd and sem indicated that rigid rod polymer polyazomethines were polymerized in the composites . the addition of pam changed the crystallization morphology and apparent crystallinity of the composites , but did not change the basal crystal form 通过对复合材料ft - ir 、紫外光谱、 waxd和sem等测试分析，表明复合材料中存在刚性棒高分子聚甲亚胺，其存在改变了pa - 6的结晶形态和表观结晶度，但尼龙6的晶型并没改变。
On the basis of antistatic polyamide developed in previous paper which is made up of pca / peg block copolymer and pa6 , the antibacterial agent and its amount are selected . the multi - functional polyamide with both lasting antistatic function and good antibacterial fimction is obtained , by adding 0 . 5 % antibacterial agent yl to antisattic system 以前面开发的pca peg嵌段共聚物pa6二元抗抗静电尼龙6为基础，筛选了抑菌剂品种及其用量。添加0 5的抑菌剂y1到二元体系中能得到一种既有永久抗静电效果又有较好抑菌效果的多功能尼龙6 。
Untreated nano - particles are apt to conglomerate , thus causing stress to centralize around the conglomeration , which results in the decreasing of impact strength . the particles " diameter of al2o3 also influences the mechanical properties of pa6 . tensile strength and tensile modulus of pa6 / nano - al2o3 composites are better than that of pad / micro - al2o3 composites whereas impact strength of the composites declines 尼龙6是一种粘弹性聚合物，在载荷的作用下容易发生粘弹性形变，当载荷较低时，随着载荷的增加而摩擦系数减小，当载荷超过一定值时，由于滑动生热，造成材料软化变形，机械强度降低，承载能力下降，摩擦系数增大。
The two constituents were compatibilized in - situ by mechanochemical reactions induced by pan - milling and the microstructure of the blend can be controlled conveniently by adjusting processing conditions . polyamide 6 / ground limestone powder ( pa6 / caco3 ) and polyamide 6 / silicon dioxide ( pa6 / sio2 ) composites were also prepared through this method . those pa6 blends and composites exhibit improved microstructure and superior mechanical properties to the systems mixed by conventional mixing methods 研究了磨盘碾磨对尼龙6的粉碎机理，制备了就地增容、微相结构可调的聚丙烯/尼龙6 ( pp / pa6 )及尼龙6 /碳酸钙( pa6 / caco _ 3 ) 、尼龙6 /纳米级二氧化硅( pa6 / nano - sio _ 2 )共混复合材料，各体系混合效果、微相结构及力学性能均明显优于采用传统混合设备制备的试样。
Plastic deformation happened in the worn surface where fe element was found , so pam micro - fiber supported part of the load and prevented the further deformation . on the condition of high speed and high load , the worn surface of pam1 / nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel , which accounted for the rather low wear mass loss . the infrared analysis showed that the a small quantity of transition of crystal form from into of nylon and its composites happened during the friction because of the high temperature and strong sheering strength 通过对复合材料耐磨性能研究表明：复合材料的摩擦系数随载荷的增加而逐步下降，且磨损表面有明显的塑性变形；从能谱分析结果来看，复合材料表面有fe的存在，表明pam微纤承受了部分载荷，并阻止了基体的进一步塑性变形及粘着转移；在高速高载时， pam1 /尼龙6磨损表面处于粘流态，并在钢环表面形成了连续的转移膜，表现出较好的耐磨损性能，且在高温和强剪切力的作用下，材料基体发生了少量的晶体向晶体的转移。
