Discussion Overview

The discussion revolves around the structure of boehmite, specifically its characteristics and applications in colloidal systems. Participants seek information and resources related to the structural properties of boehmite, particularly in the context of colloidal and polymeric applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant identifies boehmite as γ - AlOOH and requests further information on its structure.
  • Another participant provides links to resources about boehmite's crystal structure.
  • A participant inquires whether the structure of colloidal boehmite can be assumed to resemble a polymer based on its monomer structure.
  • One response emphasizes the need for a detailed description of the system to provide meaningful assistance regarding boehmite's structure.
  • A participant describes their colloidal system of boehmite rods and mentions using software to calculate free energy and molecular interactions, expressing uncertainty about the structure of the colloid molecule.
  • A request is made for publications related to the rod-like shape of boehmite and its liquid crystal phase.

Areas of Agreement / Disagreement

Participants express varying levels of knowledge and uncertainty regarding the structure of boehmite and its applications. There is no consensus on the specific structural details or the implications for colloidal systems.

Contextual Notes

Participants note the importance of specific system descriptions and the context of boehmite's use in composites and colloidal dispersions, but details about assumptions or definitions are not fully explored.

Who May Find This Useful

Researchers and students interested in materials science, colloidal chemistry, and the structural properties of boehmite may find this discussion relevant.

hello
does anyone have any idea for the structure of boehmite?
i only found that is the γ - AlOOH.

any links would be really helpfull. ty.

sorry for my english
 
Chemistry news on Phys.org
thank you very much.


i have a colloidal that is boehmite.the structure of the coloidal would be like a polymer assuming that the monomer has the structure above?

thank you.sorry for my english
 
We really can't help you much unless you completely describe your system and try to write down exactly what you want to know about the structure.

In general, Boehmite colloids are used for making composites (more recently, nano-composites) with polymers like polyamides. The boehmite particles have been observed with highly anisotropic rod-like shapes. The synthesis itself often involves a colloidal dispersion in some dilute acidic medium that, at certain concentrations exhibits a nematic, liquid-crystal phase.
 
i have a colloidal system of boehmite rods.beside the dls sls mesurments i want to calculate its free energie of the system using a programme called tinker and i also want to calculate the attraction between the molecule and the solvent using another programme called gaussian.
To run this programmes i have to give them as input the structrure of the molecule ( in this case colloid ) i want to be calculated.i have no idea what is the structure of a colloid molecule.
thank you
 
any publication about boehmite rods like shape and liquid cristal phase to give or show ?
Thank you
