Abstract
In this research, CO3Ap/gelatine scaffolds were fabricated by freeze drying method. CO3Ap powder were synthesized by reaction of phosphoric acid (H3PO4) and calcium hydroxide (Ca(OH)2). FTIR, XRD, SEM, particle size analysis and CHN showed that the synthesized of CO3Ap powder was pure CO3Ap powder. Porous gelatine scaffolds was fabricated using freeze drying method. Three porous gelatine scaffolds were synthesized at different freezing temperature of -10 °C, -20 °C and -40 °C. As a result, lower freezing temperature increases the mechanical properties of porous gelatine scaffolds from 1.01 MPa to 16.7 MPa. 5 wt.%, 10 wt.% and 15 wt.% of gelatine content and CO3Ap powder were used in this research to study the effects of the scaffolds. Besides, different freezing temperature of porous CO3Ap/gelatine scaffolds also were been synthesized. Higher gelatine content will increase the mechanical properties of scaffolds. The highest mechanical strength for porous CO3Ap/gelatine was 16.7 MPa with 15 wt.% of gelatine content at the temperature -40 °C while 0.417 MPa for porous gelatine scaffolds at the temperature -40 °C. SEM results showed the increased of particle size and pore size also will effects the mechanical behavior of the scaffolds.
