Properties of thermoplastic polyurethane adhesives containing nanosilicas with different specific surface area and silanol content
(Elsevier, 2007-09)
Thermoplastic polyurethane (TPU) adhesives containing nanosilicas with different specific surface area and silanol group content were prepared and characterized by FTIR spectroscopy, differential scanning calorimetry (DSC), ...
Electrospinning TPU/poly o-phenetidine (POEA) fibers: influence of POEA on fiber morphology
(2017-07-01)
The synthesis of poly (o-phenetidine) (POEA) was performed via chemical oxidative method and doped with dodecylbenzenesulfonic acid. Electrospun fibers of thermoplastic polyurethane (TPU)/poly o-phenetidine (POEA) blends ...
Thermally reduced graphene oxide/thermoplastic polyurethane nanocomposites: mechanical and barrier properties
(MDPI, 2021)
This work consists of studying the influence of two thermally reduced graphene oxides (TRGOs), containing oxygen levels of 15.8% and 8.9%, as fillers on the barrier properties of thermoplastic polyurethane (TPU) nanocomposites ...
Addition of nanosilicas with different silanol content to thermoplastic polyurethane adhesives
(Elsevier, 2006-08-15)
Three nanosilicas with different silanol contents were prepared by treatment of hydrophilic fumed silica with dimethyldichlorosilane. This treatment reduced the silanol content and produced the particle agglomeration of ...
Effect of cooling induced crystallization upon the properties of segmented thermoplastic polyurethanes
(De Gruyter, 2016-09)
An investigation on the cooling-induced crystallization in three thermoplastic polyurethanes based on MDI, PTMG, and 1,4-BD as chain extender with differenthard segment content is reported. Thermal transitions were determined ...
