SEM images of a PMMA powder, b chitosan powder, c TCP powder, d pure P (before degradation), e P3TC1 (before degradation), f P2TC1 (before degradation), g P1TC1 (before degradation), h P1TC2 (before degradation), i P1TC3 (before degradation), j pure P (after degradation), k P3TC1 (after degradation), l P2TC1 (after degradation), m P1TC1 (after degradation), n P1TC2 (after degradation), and o P1TC3 (after degradation). The SEM images show that TCP and chitosan induced pores for osteo-conduction after degradation; the higher TCP and chitosan content enhanced degradation process and with larger pore size
