چکیده
Abstract A considerable number of research works focus on the positive influence cellulose properties polymer-based composites and their wide range application possibilities. The present work is focused synthesis novel bio-based polyurethane (bio-PU) filled with powdered (microcellulose, MC) in an amount 5 wt.%. Bio-PU were synthesized via a non-solvent prepolymer method. First, was from diisocyanate mixture based hexamethylene polyisocyanate Tolonate™ X Flo 100 α,ω-oligo(ethylene-butylene adipate)diol which contained cellulose. Then, resulted extended by 1,4 butanediol (bio-BDO). obtained different [NCO]/[OH] molar ratios: 0.95, 1.0, 105 1.1. Special attention paid to MC phase separation between soft hard segments bio-PU studying chemical structure, morphology thermal mechanical prepared cellulose-based composites.

متن کاملBio - inspired stretchable network - based intelligent composites
The human skin hosts an array of sensors that are capable of detecting and interpreting many traits important to how we function and survive. The goal of mimicking this capability in composites to create intelligent composite materials has led to the development of a bio-inspired stretchable network composed of numerous micro-fabricated sensors capable of detecting multiple stimuli. The compone...
