Super‐hydrophobic (SH) surfaces have garnered significant attention due to their potentially diverse range of applications (e.g., self‐cleaning surfaces, waterproof fabrics, non‐stick containers, and microfluidics). The manufacturing methods SH are generally expensive often require specialized tools. In this study, we employed simplified production methods, focused on cheap chemical modification common polymers using nanocomposites create surfaces. Polymer many advantages as a coating by...

Abstract High‐dielectric constant (high‐K) polymer nanocomposites based on nematic liquid crystals and CaCu 3 Ti 4 O 12 (CCTO) nanoparticles have been prepared. The host matrix is dispersed (PDLC) in which LC (E7) droplets are different blends ratios of poly vinyl chloride/poly aniline (PVC/PANI). PDLC (PVC/PANI/E7) the appropriated ratios; (90/10/5), (75/25/5), (50/50/5) were composited with 10 wt% CCTO nanoparticles. IR spectra recorded for present a spectrum similar to that pure but...

The smectic C*-alpha (SmCα*) phase is one of the sub-phases ferroelectric liquid crystals that has drawn much interest due to its electro-optical properties and ultrafast switching. Generally observed above SmC* in temperature, SmCα* commonly shows only very narrow temperature range a few degree Celsius. To broaden phase, polymer stabilization was investigated for thermal stabilization. Two different reactive monomers were tested three mixtures, all broadened from 3 °C 39 °C. current...

We have recently reported a new 3-layer field-induced ferrielectric (SmC*Fi1_2) phase, which can be accessed either from the usual (SmC*Fi1) phase or as two-stage process initially 4-layer (SmC*Fi2) phase. Simple analytical models predict threshold fields for transitions from: (i) to synclinic (SmC*); (ii) 4- SmC*Fi1; (iii) SmC*Fi1 3 SmC*Fi1_2; and (iv)SmC*Fi1_2 SmC*. Each of these thresholds is defined by equations involving interlayer interaction strengths. deduce resulting...
