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.

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.
