“…Because the backbone of Pul is formed by glycosidic linkages of a-(1!6) D-glucopyranose and a-(1!4) D-glucopyranose units in a 1:2 ratio, Pul is a highly hydrophilic polysaccharide with rich hydrophilic groups (-OH), 31 and the hydroxyl groups in Pul are likely to form H bonds with hydroxyl, carboxyl, crystal water, etc. 32 When Pul is added, its hydrophilic groups are likely to combine with the crystal water in MCPM. It is also possible for one Pul chain to combine with others under the action of H bonds between hydroxyl groups.…”

“…It is also possible for one Pul chain to combine with others under the action of H bonds between hydroxyl groups. [32][33][34] The two effects result in a certain barrier to the contact of water molecules with the raw materials. Consequently, the production of H þ from the hydrolysis of MCPM was reduced, causing the pH to increase from 2.92 to 3.13 (1 min) and from 3.37 to 3.60 (60 min) with an increase in Pul, as shown in Figure 2 (a).…”

In this work, a modified dicalcium phosphate dihydrate (DCPD) bone cement with unique biodegradable ability in a calcium phosphate cement system was prepared by the hydration reaction of monocalcium phosphate monohydrate and calcium oxide and integration with pullulan (Pul), a non-toxic, biocompatible, viscous, and water-soluble polysaccharide that has been successfully used to improve defects in DCPD bone cement, especially its rapid solidification, fragile mechanical properties, and easy collapse. The effect of different contents of Pul on the structure and properties of DCPD were also studied in detail. The modified cement was characterised by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, ultraviolet–visible absorption, X-ray photoelectron spectroscopy analysis, and rheological property measurements. The results indicated that Pul promoted the hydration formation of DCPD, and interface bonding occurred between Pul and DCPD. With increasing content of Pul, the setting time of the DCPD bone cement increased from 2.6 min to 42.3 min, the compressive strength increased from 0 MPa to 20.4 MPa, and the anti-collapse ability also improved owing to the strong interface bonding, implying that the DCPD bone cement improved by Pul has better potential for application in the field of non-loading bone regenerative medicine compared to unmodified DCPD bone cement.
