Chemical Modification of Kraft Lignin: Effect on Chemical and Thermal Properties
Autor: Yao Chen, Nicole M. Stark, Zhiyong Cai, Charles R. Frihart, Linda F. Lorenz, Rebecca E. Ibach
Publikováno v: BioResources, Vol 9, Iss 3, Pp 5488-5500 (2014)
Esterified kraft lignins (KL) were prepared by reaction with maleic anhydride (MA), succinic anhydride (SA), and phthalic anhydride (PA) in acetone solutions. The esterified lignins were characterized using ATR-FTIR, solid state CP-MAS 13C NMR spectr

Improved Wood-Bond Strengths Using Soy and Canola Flours with pMDI and PAE
Autor: Mahsa Barzegar, Linda F. Lorenz, Rabi Behrooz, Charles R. Frihart
Publikováno v: Polymers; Volume 14; Issue 7; Pages: 1272
The surprising lack of literature on using the very common wood adhesive polymeric methylenediphenyl diisocyanate (pMDI) with protein adhesives may be because of perceived poor improvement of protein wet strength. Reacting pMDI with the flour (soy or

Specific oxidants improve the wood bonding strength of soy and other plant flours
Autor: Charles R. Frihart, Linda F. Lorenz
Publikováno v: Journal of Polymer Science Part A: Polymer Chemistry. 57:1017-1023
To meet newer environmental standards, modified plant proteins have been studied as no‐added formaldehyde wood adhesives for interior applications. Many methods have been developed to increase the wet strength of wood products bonded with soy adhes

Standard Test Method ASTM D 7998-19 for the Cohesive Strength Development of Wood Adhesives
Autor: Charles R. Frihart, Linda F. Lorenz
Publikováno v: Journal of Visualized Experiments.
The properties of cured wood adhesives are difficult to study because of the loss of water and other components to the wood, the influence of wood on the adhesive cure, and the effect of adhesive penetration on the wood interphase; thus, normal testi

Acetylation increases relative humidity threshold for ion transport in wood cell walls – A means to understanding decay resistance
Autor: Daniel J. Yelle, Sophie-Charlotte Gleber, Joseph E. Jakes, Christopher G. Hunt, Linda F. Lorenz, Stefan Vogt, Samuel L. Zelinka, Charles R. Frihart
Publikováno v: International Biodeterioration & Biodegradation. 133:230-237
The improved fungal decay resistance exhibited by modified wood has been attributed to inhibited diffusion of decay precursors and subsequent degradation products through the wood cell wall. However, data relating the effect of modification to diffus

Publikováno v: Journal of Materials Science. 54:705-718
To accelerate development of new and improved wood adhesives for engineered wood products, the optimal adhesive penetration into wood needs to be better understood for specific products and applications. Adhesive penetration includes both flow of adh
