Polymer Crystals: Structure and Morphology

Analysis of the structure and morphology of fenoxycarb crystals.

In this paper, we have explored the relationship between surface structure and crystal growth and morphology of fenoxycarb (FC). Experimental vs. predicted morphologies/face indices of fenoxycarb crystals are presented. Atomic-scale surface structures of the crystalline particles, derived from experimentally indexed single crystals, are also modelled. Single crystals of fenoxycarb exhibit a pla...

Structure and Morphology of Polymer-Stabilized Cholesteric Diffraction Gratings

Growth and Morphology of Crystals*

This issue of “FORMA” presents an English translation of Haeckel’s book “Crystal Souls”, with Alan Mackay’s introduction and detailed annotations. The tanslation was accomplished by Alan, my respectable old friend since 1950’s. When this book published in 1917, Haeckel tried to attract people to beautifully organized variety of forms exhibited by radiolaria and snow crystals, and the close simi...

1D Copper(I) Coordination Polymer [Cu(Clba2-1,2-pn)(NCS)]n: Synthesis of Microparticles and Single Crystals, Crystal Structure, and Thermal Study

In this research, 1D four-coordinate copper(I) coordination Polymer [Cu(Clba2-1,2-pn)(NCS)]n (1) with thiocyanate anion as bridging ligand, where Clba2-1,2-pn = N,Nʹ-bis(2,4-chlorobenzylidene)propane-1,2-diamine), was synthesized by slow evaporation of solvent at room temperature and characterized by elemental analysis (CHN) and single-cryst...

Dependence of the morphology of polymer dispersed liquid crystals on the UV polymerization process

Using confocal microscopy, we have studied the morphology of polymer dispersed liquid crystals ~PDLC! as a function of polymer/liquid crystal composition, polymer cure temperature, and ultraviolet ~UV! curing power and determined how this morphology affects the electro-optical properties. The PDLC morphology consists of a spongelike texture where spherically shaped liquid crystalline domains ar...
