Properties and structure of cyanate ester/polysulfone/organoclay nanocomposites [PDF]

open access: greenPolymer, 2006
In this paper, a cyanate ester (CE) matrix has been modified with polysulfone and an organic montmorillonite (Nanofil 919). The blend was thermally cured in presence of copper acetylcetonate and nonylphenol. The morphology of the cured materials was investigated by wide angle X-ray, scanning and transmission electron microscopy techniques.

Molecular design of cyanate ester resin using amino-POSS and C60 to create high-performance thermostable polycyanurate nanocomposites

open access: diamondeXPRESS Polymer Letters
The kinetics of polycyclotrimerization of cyanate ester resin (CER), viz. dicyanate ester of bisphenol E (DCBE), was studied by DSC method during its molecular design at ultra-low content (0.1 wt%) of two types of nanofillers: reactive ...

Development of kinetics sub-model of cyanate ester-based prepregs for autoclave molding process simulation

open access: bronzeHigh Temperature Materials and Processes, 2018
Autoclave molding of prepregs is an established fabrication method to produce composite components to be used in the aerospace industry and elsewhere. The process involves the excess resin to flow out and curing of the resin. The process model simulation,

High-Altitude Open-Pit Coal Mining has Changed the Sulfur Cycle and Ecological Network of Plant Rhizosphere Microorganisms. [PDF]

open access: yesEcol Evol
This study explored the changes in functional genes related to sulfur cycling and microbial diversity during different stages of succession following the ecological restoration of a mining site in a cold arid area. A total of three succession stages were selected—natural, secondary, and artificial.
