N1  - Polyetheretherketone (PEEK) is widely used in biomedical and dental 
applications due to its good mechanical strength and biocompatibility; however, its 
surface is relatively bioinert and lacks antibacterial properties. The aim of this work is to 
fabricate Poly-ether-ether ketone (PEEK) based matrix composite with eggshell 
powdered filler with 5 wt. %, 10 wt. %, and 15 wt. %. Further modified the surface 
properties via coating chitosan to enhance the surface hardness, mechanical and 
antibacterial properties. The incorporation of filler content and chitosan coating is 
verified by structural characterization using XRF, FTIR, SEM, and EDX, confirming the 
dispersion of filler in the PEEK matrix. Furthermore, the average contact angle 
measurements confirm the improved surface wettability in coated composites. The 
increasing trend in hardness and compression testing up to 10 wt.% filler concentration, 
followed by a slight decrease at 15 wt.%, indicates the effect of higher loading and 
agglomeration of particles on mechanical strength. Chitosan coating showed promising 
improved antibacterial activity against E. coli and S. aureus in antibacterial testing, with a 
visible increase in inhibition zone with increasing eggshell concentration. Overall, the 
outcomes depicted that the composite based on polymeric PEEK matrix reinforce with 
eggshell and chitosan coating can effectively enhance the surface properties, mechanical 
performance, and antibacterial behavior of composites, making them viable replacement 
of dental implant
