This study introduces an effective and facile method for fabrication of natural polymer microfibers. The microfibers used in this study were obtained from red algae biomass. For this, we used a cellulase-based enzyme reaction uniformly disconnected entangled fiber networks to single microfibers. Then, the surface of microfibers was chemically modified by grating zwitterionic biopolymers made of methacryloyl phosphatidyl choline and butyl methacrylate. Use of atom-transfer radical-polymerization (ATRP) allowed us to incorporate brushes as well as gels onto the microfibers. In this study, we characterize the surface morphology and interfacial property of surface-modified algae microfibers by using TEM, SEM, and contact angle measurements. Also, we carry out suspension rheology studies in order to figure out how the modified microfibers interacts each other in dense suspensions. |
