Cure Kinetic of Polyurethane/Fluorinated POSS Hybrid
One of the decisive factors in obtaining the desired properties in coatings is their complete curing, which necessitates the study of kinetics of curing. In recent years, many studies have been conducted on the use of polyhedral oligomeric silsesquioxane (POSS) in coatings. Creating functional groups on POSS and using it in formulation can create new or improve the properties of coatings. I...

متن کاملEffects of organophilic-modified attapulgite nanorods on thermal and mechanical behavior of segmented polyurethane elastomers
The effects of different grafting content of 4,4′-methlenebis(phenyl isocyanate)-modified attapulgite (ATT-MDI) on thermal and mechanical properties of segmented polyurethane (PU) elastomers were investigated. The ATT-MDI nanorods with different grafting content were prepared by treating ATT with heat and acid followed by grafting with MDI molecules. MDI-modified ATT were characterized by trans...
متن کاملPreparation and Characterization of Waterborne Polyurethane Modified by Nanocrystalline Cellulose
Nanocrystalline cellulose (NCC) was used as a modifier for waterborne polyurethane (WPU) to investigate the water and ethanol resistance of WPU-NCC composites. The NCC surface was modified with γ-glycidoxypropyltrimethoxysilane (GPTMS) and γammnonimpropylmethyldimethoxysilane (APMDS) to improve its compatibility with waterborne polyurethane (WPU), as indicated by the contact angle (CA). The cha...
متن کاملSynthesis and characterization of organically modified attapulgite/polyurethane nanocomposites
Polyurethane (PU) nanocomposites filled with attapulgite (ATT) nanorods were synthesized and characterized with thermal analysis, dynamic mechanical analysis (DMA), and mechanical testing. The formulations were based on 4,4′-methylene bis(phenyl isocyanate) (MDI), polytetrahydrofuran, 1,4-butanediol, and inorganic ATT premodified with MDI. The original and premodified ATT (ATT–OH and ATT–MDI) n...
