Abstract
Polyvinylidene fluoride and its copolymers are a well-known family of low-cost ferroelectric materials widely used for the fabrication of devices for a wide range of applications. A biocompatibility, high optical quality, chemical and mechanical durability of poly(vinylidene fluoride–trifluoroethylene), (P(VDF–TrFE)), makes it particularly attractive for designing of effective coating layers for different diagnostic techniques. In the present work, the nonlinear optical characterization of P(VDF-TrFE)-coating films deposited onto a glass substrate was done. Advantages of the coating application for cells/substrates in the field of multiphoton imaging the efficiency of such coating layer for long-duration characterization of so-called harmonic nanoparticles (HNPs) were shown. The influence of glass surface protection by P(VDF-TrFE) film from an effect of HNPs sticking to the walls of the flow-cell was analyzed for effective studying of the optical harmonics generation efficiency of HNPs making the analysis more robust.
Highlights
We should mention the utilization of the PVDF-based composites as they superhydrophobic and antibacterial material [23,24] that make them perspective for designing of effective coating layers
Analysis of theeffects absorptive responses
An applicability of the P(VDF-TrFE) coating at the glass substrate as a part of experimental cell was studied for the third harmonic generation effect in colloids of zinc oxide (ZnO)
Summary
P(VDF-TrFE) copolymer with chemical formula (CH2 -CFH)n It is optically transparent, semi-crystalline piezoelectric polymer, where chains exhibit strong preferential orientation [1,2,3,4]. This lightweight, low cost, ultra-sensitive, and high deformable polymer is mainly used in areas requiring excellent chemical resistance, high purity, and excellent mechanical properties [5]. We should mention the utilization of the PVDF-based composites as they superhydrophobic and antibacterial material [23,24] that make them perspective for designing of effective coating layers
