Water resistant, sturdy, degradable and recyclable rosin-grafted cellulose composite paper


Petroleum-based plastics are helpful, however they pose an enormous risk to the setting and human well being. The event of sustainable cellulose paper supplies with glorious mechanical and water-resistance properties to interchange plastics is very fascinating but in addition difficult. Herein, we report a brand new type of rosin-based modifier synthesized from absolutely hydrogenated rosin and (3-glycidoxypropyl)triethoxysilane, which might covalently bind with cellulose fiber networks to enhance the hydrophobicity and weaken the capillarity of cellulose paper. The rosin-grafted cellulose composite paper exhibits a singular mixture of water resistance (water absorption of 19.2% and 37.9% in 25 and 90 °C water, respectively) and excessive power (tensile power of 47.9 MPa and Younger’s modulus of two.32 GPa). Furthermore, the rosin-grafted cellulose composite paper might be utterly degraded when buried in soil for as much as 100 days, and it may be recycled when handled with an alkali. These spectacular performances make rosin-grafted cellulose composite paper turn into an eco-friendly different materials to interchange plastics within the fields of straws, bins, cups, baggage and so forth.
