    • A method for making a series of nanoscale microstructures, including helical microstructures and cylindrical microstructures. This method includes the steps of: (1) forming a chiral block copolymer containing a plurality of chiral first polymer blocks and a second polymer blocks wherein the chiral first polymer blocks have a volume fraction ranging from 20 to 49%; (2) causing a phase separation in the chiral block copolymer. In a preferred embodiment, the chiral block copolymer is poly(styrene)-poly(L-lactide) (PS-PLLA) chiral block copolymer, and the copolymerization process is a living copolymerization process which includes the following steps: (a) mixing styrene with BPO and 4-OH-TEMPO to form 4-hydroxy-TEMPO-terminated polystyrene; and (2) mixing the 4-hydroxy-TEMPO-terminated polystyrene with [(η3-EDBP)Li2]2[(η3-nBu)Li(0.5Et2O)]2 and L-lactide in an organic solvent preferably CH2Cl2 to form the poly(styrene)-poly(L-lactide) chiral block copolymer. Transmission electron microscopy (TEM) and small X-ray scattering (SAXS) studies show that when the volume fraction of poly(L-lactide) is about 35-37%, nanoscale helices with a pitch of 43.8 nanometers and a diameter of 34.4 nanometers were observed.
    • 制备一系列纳米级微观结构的方法,包括螺旋微结构和圆柱微结构。 该方法包括以下步骤:(1)形成含有多个手性第一聚合物嵌段的手性嵌段共聚物和第二聚合物嵌段,其中手性第一聚合物嵌段具有20至49%的体积分数; (2)引起手性嵌段共聚物中的相分离。 在优选的实施方案中,手性嵌段共聚物是聚(苯乙烯) - 聚(L-丙交酯)(PS-PLLA)手性嵌段共聚物,共聚方法是一种活性共聚方法,其包括以下步骤:(a) 用BPO和4-OH-TEMPO形成4-羟基-TEMPO封端的聚苯乙烯; 和(2)将4-羟基-TEMPO封端的聚苯乙烯与[(η3 -EBP)Li 2 N 2 [(η 在有机溶剂中,Li(0.5Et 2 O)] 2 N和L - 丙交酯 优选CH 2 2 Cl 2以形成聚(苯乙烯) - 聚(L-丙交酯)手性嵌段共聚物。 透射电子显微镜(TEM)和小X射线散射(SAXS)研究表明,当聚(L-丙交酯)的体积分数为约35-37%时,具有43.8纳米的间距和34.4纳米的直径的纳米级螺旋 被观察到。

    • A method of making flower-shaped bath scrubber uses a bar as the support to pierce through a netting band which is folded at one end, then use the bar as an axis to have the remaining netting band run through one end of the bar. Then move the netting band laterally along the bar to another end and have the remaining netting band run through the bar from another end. The foregoing process is repeatedly performed until the netting band is completely disposed on the bar. Then fasten one end of the netting band and remove the bar. The wound around netting band then may be unfolded and stretched to form a shape desired. After another fastening, a flower-shaped netting bath scrubber will be formed.
    • 制作花形浴洗涤器的方法是使用棒作为支撑件刺穿通过在一端折叠的网带,然后使用棒作为轴使剩余的网带穿过条的一端。 然后将网状带横向移动到另一端,并且剩余的网带从另一端延伸通过杆。 重复执行上述过程,直到网带完全设置在条上。 然后将网带的一端固定并取出。 然后围绕网带的伤口可以展开并拉伸以形成所需的形状。 在另一个紧固后,将形成一个花形网状洗浴洗涤器。
