Commonly used absorbable suture materials.

	Name	Structure	Characteristic	Preparation Method	Ref.
Natural absorbable suture material	Catgut/chrome gut	Monofilament	Monofilament, easy to degrade, low tensile strength, susceptible to bacterial infection	Washing and drying	[102]
	Regenerated cellulose	Monofilament	Ideal biodegradability and mechanical properties	Wet spinning	[104]
Synthetic absorbable suture material	P3BV-co-HB	Monofilament	Strong toughness, biodegradable, non-toxic, promote cell proliferation	Blend electrospinning	[106,108]
	PCL	Monofilament or woven	Good biocompatibility, degradability, mechanical properties and shape memory properties are excellent	Blend electrospinning	[110]
	PDO	Monofilament	Colorless, biodegradable, mechanically flexible	Blend electrospinning	[116]
	PLA	Monofilament	Biocompatible, good degradability	Blend electrospinning	[117]
	PLGA	Monofilament	Degradable, non-toxic and harmless, good tensile properties	Blend electrospinning	[118]
	PU	Monofilament	Biocompatible, degradable	Blend electrospinning	[120]
