4-tert-butylstyrene-EPDM-divinylbenzene graft terpolymer (PBED) was prepared by graft cross-polymerization in toluene using BPO as an initiator. The gel-PBED and solPBED were isolated from extraction of tetrahydrofuran (THF), and then they were identified by IR spectroscopy. The maximum oil-absorptivity of gel-PBED produced from the optinum reaction conditions was 8 420% but its swelling rate was very low. The highest oil-absorptivity of photocrosslinked sol-PBED film was 5 800%. Although its oil absorbency was not as high as gel-PBED' s, swelling rate was higher than that of gelPBED and was suitable for commercial purpose. After swelling in oil, neither gel PBED nor photocrosslinked sol-PBED film having high oil-absorptivity had sufficient mechanical strength to be taken out of oil wholly. As is known, composite technique is one of the useful methods for reinforcing them. Fibers, sponges and non-woven cloths were used as reinforcers or supporters in this work. Oil-absorptivities and swelling kinetics were evaluated by method ASTM (F726 - 81 ) and an experimental equation. The mechanical properties and the morphologies of some composites were measured by tensile tester and SEM , respectively. 相似文献

基于动态位置约束的布料变形方法 总被引:1,自引:0,他引:1
在服装动画中,基于物理的方法通常可以产生较好的动画效果。但对于特定区域,如紧贴人体的服装区域等,使用物理方法驱动其变形时,通常需要增大服装与人体面之间的摩擦力,以保证二者相对正确的位置关系。而过大的作用力会引入数值计算问题,从而降低系统稳定性。针对此问题,提出一种动态位置约束的布料变形方法。首先建立服装顶点与人体皮肤面之间的映射关系;其次,基于人体皮肤变形前与变形后的数据求解出仿射变换,并将仿射变换应用到变形前的服装数据上,以求得服装相对人体面的正确位置及运动;最后,通过实验验证了方法的有效性。方法不仅可以对服装指定区域实施持续不变的位置约束,也可以在动画过程中对服装整体或局部动态施加或者解除约束,与物理方法结合使用,能够保持动画系统的动力学特性。 相似文献
