MatNavi is one of the world's largest materials databases of polymer, ceramic, alloy, superconducting material, composite and diffusion.

Polymer Database (PoLyInfo)

Outline

Polymer Database "PoLyInfo" systematically provides various data required for polymeric material design. The main data source is academic literature on polymers. Information on polymers including properties, chemical structures, IUPAC names, processing methods of measured samples, measurement conditions, used monomers and polymerization methods are stored in a object database. About 100 types of properties including thermal, electrical and mechanical properties are covered. Homopolymers, copolymers, furthermore polymer blends, composites and compounds that consist of homopolymers and copolymers are open to the public. Property Prediction Subsystem, Nomenclature System and NMR Database are also available as advanced functions.

Database

Polymer Search
Polymer Search is done by specifying the polymer name, type, chemical formula, material type, properties and reference publication. There are "Basic" (simple condition setting) and "Advanced" (detailed condition setting) searches, and furthermore "Text" (text search) that searches all display contents.

Polymer Structure Search
A search can be done by specifying the type and quantity of an atom group included in the constitutional unit of the polymer, or by drawing the chemical structure using a modeling tool.

Easy Browse
The user can search from the "Property table", "Popular polymer" or "Plotted data".

Monomer Search
Monomer Search is done by specifying the monomer name, registry No., class, molecular formula and molecular weight.

Property Prediction System
As a complement to the database, this system predicts values of Tg, Tm, solubility parameter, surface tension, interfacial tension, dielectric constant, refractive index, density, tensile strength and tensile strength at break.

Nomenclature System
The nomenclature System can create the IUPAC structure name by using a modeling tool to draw the chemical structure of the polymer constitutional unit.

NMR Database
1H, 13C NMR spectra of 154 samples are provided with assignment data.
