Tensile tests of PEG-Dop, PEG-Dop/Coll, composite hydrogel PEG-Dop/HAp and composite mixture PEG-Dop/Coll/HAp.

	Young’s Modulus (kPa)	Tensile Strength (kPa)	Strain (%)
PEG-Dop	15.2 ± 4.7	18 ± 1.3	182.3 ± 42.7
PEG-Dop/Coll	86.9 ±18.8	66.7 ± 6.5	100.9 ± 21.4
PEG-Dop/HAp	96.6 ± 4.9	45.2 ± 1.2	64.7 ± 3.0
PEG-Dop/Coll/HAp	181.5 ± 39.3	88.5 ± 9.5	61.3 ± 20.6

Concentration of the different components is as follows: 15% (w/v) PEG-Dop, 2.5% (w/v) HAp, 0.1% (w/v) Coll. Mean value ± standard deviations are given, n = 3.
