Figure 4. Increasing PEG mass in alginate-PEG gels enhances creep and leads to a higher loss modulus.

Figure 4.

Creep tests for gels of alginate grafted with A, 2, B, 5, and C, 20 kDa of PEG. Frequency-dependent tests for gels of alginate with A, 2, B, 5, and C, 20 kDa of PEG. Storage modulus and loss modulus were normalized by the storage modulus at 1 Hz.
