Excess CPAM solution will cause the CL colloid to flocculate prematurely and reduce the amount of CL adsorbed. Stable nano-lignin particles were obtained with an optimum mass ratio of 100:1 of CL:CPAM. The CL:CPAM of 100:1 resulted in a zeta potential value of −13 mV, negative enough to stabilize the new formed nano-lignin particles.
