One area where graded cellulose shows immense potential is in the fabrication of composite materials. These materials combine two or more constituents to yield superior properties that cannot be achieved by any of the individual components alone. By integrating graded cellulose with other biopolymers or even synthetic polymers, researchers can design composites with enhanced mechanical strength, improved thermal stability, and tunable degradation rates. These composites find utility in packaging, construction, and even in the automotive industry where lightweight yet strong materials are sought after.

The working mechanism of methyl hydroxyethyl cellulose, MHEC (Mw = 2.5 · 105 g/mol, DSmethyl = 1.81, MShydroxyethyl = 0.15) as water retention agent in cement was investigated. First, the hydrocolloid was characterized and its performance as non-ionic water retention agent was determined employing the filter paper test. Also, water sorption and swelling of individual MHEC fibers under conditions of different humidities were monitored by ESEM imaging. Second, its working mechanism was established. It was found that at low dosages, MHEC achieves water retention by intramolecular sorption of water and concomitant swelling while at higher dosages, MHEC molecules agglomerate into large hydrocolloidal microgel particles (d > 1 μm) which effectively plug the pores in the mortar matrix. MHEC association was evidenced by an exponential increase in solution viscosity as concentration rises, a strong increase in the hydrodynamic diameter of solved MHEC molecules, and a noticeable reduction of surface tension.
