Selective assembly of nanoparticles on block copolymer by surface modification
We have developed a method to selectively deposit nanoparticles on the ordered nanoscale elements of PS–PI–PS (polystyrene–polyisoprene–polystyrene) block copolymer film. The process utilizes reactive ion plasma to selectively modify the PS surface with amine groups to electrostatically attract negatively charged Au nanoparticles. In spite of the strong interparticle Coulombic repulsion, the de...
متن کاملControlled assembly of Janus nanoparticles.
Janus nanoparticles were prepared by interfacial ligand exchange reactions of octanethiolate-protected gold (AuC8) nanoparticles with 3-mercapto-1,2-propanediol (MPD) at the air/water interface. AFM and TEM measurements showed that the resulting particles formed stable aggregates in water with dimensions up to a few hundred nanometers, in sharp contrast to the original AuC8 particles and bulk-e...
متن کاملBarium Titanate Nanoparticles in Block Copolymer
Cubic BaTiO3 particles of∼10 nm were crystallized predominantly within the hydroxylated polybutadiene matrix of a phase separated triblock copolymeric thin film of polystyrene-polybutadiene-polystyrene (Kraton D1102). The barium titanated Kraton thin film had remnants of the cylindrical morphology of a plain Kraton thin film with an interdomain spacing of ∼23 nm. The procedure of barium titanat...
متن کاملBioinspired assembly of functional block-copolymer nanotemplates.
A new concept on bioinspired assembly of functional diblock copolymers, capable of forming different microstructures through nucleobase-induced supramolecular interactions, has been explored. In this paper, a new series of uracil-functionalized poly(ε-caprolactone)-b-(4-vinylbenzyl uracil)s (PCL-b-PVBU) have been prepared which exhibit a high self-complementary ability in solution and solid sta...
متن کاملDirected Self-Assembly of Block Copolymer, No1
/Description The PS-rich and neutral PS-b-PMMA block copolymer (BCP) films were spin coated on the neutral random copolymer hydroxyl-terminated PS-r-PMMA layers grafted on the native oxide and 50 nm thick PECVD amorphous silicon oxide layers. Relationship between the grafting density of BCP and surface density of hydroxyl moiety on silicon oxide is discussed. Furthermore, optimization of anneal...
