Enhancement of Chloroprene/Natural/Butadiene Rubber Nanocomposite Properties Using Organoclays and Their Combination with Carbon Black as Fillers.

Organoclay nanoparticles (Cloisite C10A, Cloisite C15) and their combination with carbon black (N330) were studied as fillers in chloroprene/natural/butadiene rubber blends to prepare nanocomposites. The effect of filler type and load on the physical mechanical properties of nanocomposites was determined and correlated with its structure, compatibility and cure properties using Fourier Transformed Infrared (FT-IR), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and rheometric analysis. Physical mechanical properties were improved by organoclays at 5-7 phr.

Effects on Lignin Redistribution in Fibres Pre-Treated by Steam Explosion: A Microscale Study to Cellulose Accessibility.

The objective of this study was to investigate structural changes and lignin redistribution in pre-treated by steam explosion under different degrees of severity (S), in order to evaluate their effect on cellulose accessibility by enzymatic hydrolysis. Approximately 87.7% to 98.
