Application

Octadecyl isocyanate (n-octadecyl isocyanate) was employed for chemical modification of:
  • surface of cellulose nanocrystals to promote interfacial filler/matrix interactions
  • poly (2-hydroxyethyl methacrylate) (pHEMA) films, to investigate in vitro hemocompatibility assay using freshly drawn human whole blood
  • cellulose nanocrystals (or whiskers) and microfibrillated cellulose (MFC)

Cellulose nanocrystals (or whiskers) and microfibrillated cellulose (MFC) were successfully obtained from sisal fibers and modified with n-octadecyl isocyanate (C(18)H(37)NCO) using two different methods with one innovation that consists of an in situ solvent exchange procedure. The surface chemical modification

Cellulose nanocrystals have been prepared by acid hydrolysis of Luffa cylindrica fibers. The acid-resistant residue consisted of rod-like nanoparticles with an average length an diameter around 242 and 5.2nm, respectively (aspect ratio around 46). These cellulose nanocrystals have been used

Albumin-scavenging surfaces decorated with n-alkyl chains represent an established strategy for blood-contacting applications. To evaluate this concept, a set of poly (2-hydroxyethyl methacrylate) (pHEMA) films modified with different amounts of octadecyl isocyanate (C18) was investigated in an in vitro hemocompatibility
