Summary of slice layer stripping method.

Authors	Materials Used	Stripper	Key Features	Strengths	Limitation	Ref.
Zhou et al.	NiAl-LDH	Formamide	Ultrasound conditions	Most effective; dissolves LDHs sheets	Dissolves LDHs sheets	[49]
Hibino et al.	MgAl-Gly LDHs	Formamide	Stir for a few minutes at room temperature	Fast gradual change without heating and reflux conditions	-	[53]
Gong et al.	Nitrate-type magnesium aluminum hydrotalcite modified by sodium dodecyl sulfate intercalation modification	Chloroform	Ultrasound conditions	-	Chloroform is sensitive to light and forms toxic gas when exposed to oxygen	[54]
Dai et al.	CTA-Mt (Organic montmorillonite)	Chloroform	Ultrasound conditions	Chloroform is sensitive to light and forms toxic gas when exposed to oxygen	-	[55]
Liang et al.	LDH intercalated with acetate ion	Water	Ultrasound conditions	Environmental protection, non-toxic, low price	-	[56]
Ma et al.	Synthesis of amino acid intercalated aluminum-magnesium hydrotalcite in a system with pH greater than amino acid isoelectric point	Water	pH is lower than the isoelectric point of amino acids, ultrasound, heating	Environmental protection, non-toxic, low price	-	[57]
Song et al.	Mt	HTPB (hydroxyl terminated polybutadiene)	353 °C	Efficient and can be completely stripped	-	[58]
Hu et al.	Layered dihydroxy compound, Mt	PLA (polylactic acid)	185 °C hydrothermal	Stripping agent is easy to degrade	-	[50]
