All the articles I have found are nanocomposites with amorphous silica nanoparticles. Is nanoquartz hard to obtain or it does not improve any properties of a polymer?
Please use the correct key words and try search again. Be more persistent.
Go to advanced search and play with it in Scopus, WoS, and Google Scholar and a review articles.
Scopus is the best in filtering by country/institution/author, Web of Science is the best for refining search results by key words (if it can help), Google Scholar is good for hard cases and long search parameters - fast operating, easy add and exclude key words and their combinations, etc. If nothing works - find a proper review article, search text for required key words and go to references. Usually it gives a lot of valuable (all of them!) links.
example:
https://scholar.google.pl/scholar?hl=en&as_sdt=0%2C5&q="quartz+nanoparticles"+AND+"polymer"&btnG=
Because most often you will find it not as quartz but as silica nanoparticles. You will find plenty of these papers.
nano-quartz is not nanoparticle, it is a nano crystal, so the key words should be "nano-quartz composite" or " quartz nanocrystals composite" , etc . I checked through google and found enough refs.
Do not know about 'crystal' quality of quartz nano fibres. I am quite certain that pure quartz nanoparticles (at least one dimension 100 nm or smaller, except maybe fibres) are not obtained from top down methods. I was not aware of any bottom up synthesis producing quartz nanoparticles. By milling you don not reach nanoscale for most of particles. By milling you obtain particles with amorphous outer layer. Few nano dust particles generated will consist out of amorphous silica. Amorphous silica layer may be dissolved in hydro fluoric acid, however, resulting surface than contains fluorine.
Searching "nano-quartz composite" leads to lot of references, but do not include nano-quartz, only a lot of composite with other nanoparticles.
One exception - Article Hydrothermal Synthesis of Quartz Nanocrystals
Nevertheless, due to easy availability studies with amorphous silica dominates.
@Titus Sobisch
Thank You for Your reply. It was very helpful.
@Ievgen Obraztsov
I tried various combinations of keywords. For example:
"quartz nanoparticles" AND "composite" AND "polymer" AND "mechanical properties" -fused
None of the papers found were useful in determining mechanical properties of polymer-quartz nanocomposites. Anyway your guide on database search will definitely be useful for me in the future. Thank you for that.
@Igor Levitsky
I did try: "nano-quartz composite" and went through lots of papers but none of them was useful for determining properties of polymer-nanoquartz composites, especially mechanical properties.
You said: "nano-quartz is not nanoparticle, it is a nano crystal"
Could you link to any definition of nanoparticle that says nanoparticles can't have crystalline structure.
Your first replay was just insulting.
Michal, the first link found through google using key word "nano-quartz composite " was :
Preparation and mechanical properties of nano-quartz fiber filled ...
www.hanser-elibrary.com/doi/abs/10.3139/120.111061by QY Luo - 2017Preparation and mechanical properties of nano-quartz fiber filled PMMA composites. Materials Testing: Vol. 59, No. 7-8, pp. 708-712. https://doi.org/10.3139/ ...
As you can see nothing complicated if use even the google. Sci Finder definitely should provide more. The common practice is to get the first article and take the refs. from there. Sorry for "insulting" but I was really surprised of such kind of problem
