Microfluidic technology is a relatively new field among the various conventional bulk techniques employed for nanomaterial synthesis. Nanoparticles (NPs) produced using such methods generally have poor surface features, morphology, uncontrolled size and broad distributions. NPs especially used in biomedical sector require degree of control over their size, polydispersity to improve functionality. To synthesize NPs, microfluidic devices are ideal as parameters mixing rates, flow volumes, multiphase reactions can be controlled on micro/nanoscale. There several strategies challenges synthesis nanoparticles from organic inorganic materials platform. The faced during design implementation these devices, large scale production interaction with soft lithography materials, which overcome by use technique conjugation microfluidics, parallelisation processes search fabrication materials.

Antifouling (AF) nanocoatings made of polydimethylsiloxane (PDMS) are more cost-efficient and eco-friendly substitutes for the already outlawed tributyltin-based coatings. Here, a catalytic hydrosilation approach was used to construct design inspired by composite mosquito eyes from non-toxic PDMS nanocomposites filled with graphene oxide (GO) nanosheets decorated magnetite nanospheres (GO-Fe3O4 nanospheres). Various GO-Fe3O4 hybrid nanofillers were dispersed into resin through solution casting method evaluate structure-property relationship. A simple coprecipitation procedure fabricate an average diameter 30-50 nm, single crystal structure, predominant (311) lattice plane. The uniform bioinspired superhydrophobic PDMS/GO-Fe3O4 nanocomposite surface produced had micro-/nano-roughness, low surface-free energy (SFE), high fouling release (FR) efficiency. It exhibited several advantages including simplicity, ease large-area fabrication, simultaneous offering dual micro-/nano-scale structures simply via one-step process wide variety materials. superhydrophobicity, SFE, rough topology have been studied as properties unfilled silicone nanocomposites. coatings' physical, mechanical, anticorrosive features also taken account. Several microorganisms employed examine resistance coated specimens 1 month. Good dispersion fillers in coating until wt % achieved highest water contact angle (158° ± 2°), lowest SFE (12.06 mN/m), improved bulk mechanical anticorrosion properties. well-distributed (1 nanofillers) nanocoating showed least biodegradability against all tested [Kocuria rhizophila (2.047%), Pseudomonas aeruginosa (1.961%), Candida albicans (1.924%)]. We successfully developed non-toxic, low-cost, economical nanostructured FR coatings long-term ship hull This study may expand applications bio-inspired functional materials because multiple AF, durability hydrophobicity both important industrial applications.
