“…A considerably high fraction of H aggregate was found in the multilayer of CuPc . Based on the absorbance studies, we infer edge on stacking H type of aggregate the CuPc molecules in the PVDF matrix which leads to splitting of Q‐band commonly named as Davydov splitting . The maximum intensity of higher energy level was relatively higher than the lower energy maximum which represents the formation of dominant α‐CuPc aggregate in the nanocomposite multilayers.…”

“…Embedding these molecules in the fluorinated polymer with higher dipole moment such as PVDF might result in the significant dipole–dipole interaction between the CuPc molecule and PVDF. Such interactions may result in a shift in the Q‐band absorbance toward the red side of the visible spectrum …”

Engineering the surface morphology with optimized crystallinity is very crucial for practical applications such as energy storage, electromechanical devices, and self‐cleaning. Organic nanocomposites permit one to tune the dielectric properties by controlling the crystallinity and surface morphology. Here, we report our investigation on metallophthalocyanines of nickel and copper as an organic additive to poly(vinylidene fluoride) (PVDF) to modify the structural, optical, wetting, and electrical properties of the nanocomposite multilayers deposited using Langmuir‐Schaefer method. The incorporation of the metallophthalocyanines in the nanocomposite multilayers was confirmed from the signature Bragg peaks, and the fingerprint absorbance using grazing incidence X‐ray diffraction and Fourier transform infrared spectroscopy, respectively. Aggregation behavior of the metallophthalocyanines in the polar matrix of PVDF was studied using ultraviolet–visible spectroscopy. Surface morphological studies using field emission scanning electron microscopy on the nanocomposite multilayers show the presence of both spherical crystallites and rod‐like structures which depends upon the composition and nature of metal in metallophthalocyanine. The surface wettability of these multilayers was investigated using static and dynamic contact angle studies. A significant enhancement in the dielectric constant has been observed for both nanocomposites relative to the pristine multilayer of PVDF. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
