“…27 Furthermore, they suggested that the detailed distribution of the ligand brush could be important, particularly because the mobility of the grafting points could result in Janus-type particles. 8,9 Again, the SCFT is fully capable of explicitly including grafted chains rather than just assigning a gradual profile to the particle. There is one technical difficulty in that the mesh must be particularly fine next to the particle (i.e., grafting surface), but there is an efficient way of dealing with this by overlaying two separate coordinate systems.…”

Self-consistent-field theory is used to predict the center-of-mass distribution of spherical nanoparticles embedded in the lamellar phase of a diblock copolymer melt. The calculation is performed in the dilute limit, where the particle-particle interactions have a negligible effect on the distribution. We investigate how the distribution is affected by particle radius R, surface affinity ΛN, diblock segregation N, diblock composition f, and invariant polymerization index N h . While the preferred location of the particles (i.e., interface or domain center) is primarily controlled by ΛN, the degree of particle localization depends on several factors. Larger values of R, N, and N h all tend to produce narrower particle distributions.

“…This can be compared with the recent study on the self-assembly of PS-coated gold nanoparticles within PSt-b-P2VP diblock copolymers. [11][12][13][14] In that case, near equilibrium morphologies could be obtained by slow evaporation of a neutral solvent. In contrast, the ordering of thin films in the system described above was achieved by fast evaporation of solvent under a high humidity condition.…”

“…Furthermore, it is well acknowledged that incorporating nanoparticles into a polymer matrix can have a significant influence in the properties of the binding matrix, including mechanical strength, conductivity, permeability and catalytic activities (Chiu et al 2005). Normally, metal nanoparticles/polymer nanocomposites can be synthesized through ex-situ and in-situ approaches.…”

Polymer-based nanocomposites have attracted a lot of attention for amperometric biosensor development due to their general physical and chemical properties including biocompatibility, film-forming ability, stability and different functional groups that can be bonded with other biomolecues. In this study, poly-4-vinlyridine homopolymer (P4VP) and polylactic acid-block-poly(2-vinylpyridine) block copolymer Nanokomposit polimer bagi pembangunan biosensor amperometrik menarik banyak perhatian kerana sifat fizikal dan kimia am mereka termasuk keserasian-bio, keupayaan pembentukan filem, kestabilan dan bergantung kepada kumpulan berfungsi yang berkemampuan untuk terikat dengan biomolekul lain. Dalam kajian ini, poli-4-vinilpiridin (P4VP) dan polilaktik asid-blok-poly (2-vinilpiridin) (PLA-b-P2VP) telah digunakan untuk dihibridkan dengan prekursor emas berdasarkan gabungan antara nitrogen kumpulan piridin daripada P4VP atau P2VP blok dengan prekursor emas (Au 3+
