Materials commonly used in adhesion prevention and a brief description of possible reasons for efficacy in adhesion prevention. Adapted from [10].

Material	Reasoning for Efficacy
Polytetrafluoroethylene (PTFE)	Physiologically inert Low adhesiveness with cells/tissues Separates damaged surfaces during wound healing without degradation Biocompatible
Polylactic acid (PLA)	No specific binding site with cells/tissues on polymer matrix Low adhesiveness with cells/tissues Separates damaged surfaces during wound healing without degradation Biocompatible (FDA approval for human use in orthopedic and neurosurgical operations) Biodegradable
Polyethylene glycol (PEG)	High mobility and steric stabilization effects in aqueous solution Low adhesiveness with cells/tissues Biocompatible
PLA-PEG	Low adhesiveness with cells/tissues Flexible and hydrophilic Biocompatible Biodegradable
Hyaluronic Acid (HA)	Wound healing properties High viscosity when dissolving by water or body fluid Muco-adhesive property in solid state Biocompatible Bioresorbable
Alginate (ALG)	Wound healing properties Muco-adhesive property in solid state Partially crosslinking by multi-valence positive charged ions in body fluid Biocompatible Bioresorbable
Cellulose (oxidized regenerated) (ORC)	Wound healing properties, in terms of re-epithelialization Muco-adhesive property in solid state Biocompatible Bioresorbable
Carboxymethyl cellulose (CMC)	Remained on the injury surfaces during wound healing Muco-adhesive property in solid state Delayed bioresorption Biocompatible
Icodextrin	Metabolized into oligosaccharides by the α-amylase in the body Delayed bioresorption in peritoneal cavity Remained on the injury surfaces during wound healing Biocompatible
