. Hybrid fillers, designated as LS-CB particles, was prepared from LS and CB. Carbon black particles.The LS-CB particles in rubber compounds contained LS and CB in the weight ratio 10:90 and 20:80, while LS-CB particles used in characterization by Raman spectroscopy contained LS and CB in weight ratio 3:1 and 1:1. A higher lignin concentration in specimens for Raman spectroscopy accentuated the interactions and resulted in higher signal fidelity
