Poly(ferrocenyldimethylsilane-b-dimethylsiloxane) microsphere with shell thickness controllable structure prepared through self-assembly

A novel approach was applied to prepare shell thickness controllable magnetic microsphere precursor through the self-assembly of PDMS homopolymer with PFS-b-PDMS in selective solvent and adjusting the prepared conditions of samples such as temperature and aging time. The magnetic microsphere precursor provided with adjustable dimension of shell thickness 15, 40 and 90 nm, respectively, which made it possessing various potential applications in biomedical and separating engineering fields.
