ABSTRACTWe report on the formation of hierarchical nanostructures of Au, Pt, Fe2O3 and PdO2 using a hybrid technique combining laser interference patterning (LIP) and block copolymer phase separation (BCPS). By varying the loading time of the block copolymer with metallic salts and the laser interference technique, different types of hierarchical square, triangular, linear and circular arrays can be formed. Such a robust method can be applied to other metallic and ceramic materials and has potential for use in the large-scale production of nano-catalysts, photonics, optoelectronics, MEMS devices and bio-sensors.

Anti-fouling PLA hollow fibers were fabricated using synthesized PLA-PEG-PLA copolymer as an additive to improve the hydrophilicity. The tri-block copolymer was prepared by ring-opening polymerization and a hydrophilic copolymer processing good compatibility with PLA molecule was obtained and utilized to fabricate membrane with PLA by NIPS. Elemental analysis showed that PLA-PEG-PLA could stably exist in membranes and endow the membrane with persistent hydrophilic. Thus the contact angle decreased nearly 20o with 5% PLA-PEG-PLA content, resulting in higher water permeability and BSA rejection which indicated the anti-fouling property of PLA membrane was improved.
