Synthesis of copolymer-g-PLA layered silicate CNPs includes the following
steps: (1) 3.5 g of copolymerwas dissolved in 20mLLA by intensive
mixing at 40 °C up to the formation a homogeneous viscous
product; (2) 0.175 g of any clay (Na+-Mt, Ag+-Mt or ODA-Mt as
catalyst-nanofillers) was dissolved in 5 mL LA by intensive mixing at
room temperature for 6 h up to fully intercalation of LA monomer between
silicate interlayer species, and (3) both solutions of copolymer
and inorganic or organic clays, were placed in a specially constructed
vacuum (600 mm/Hg) micro-reactor with Dean-Stark unit and mixed
at 80 °C up to previously fixed phase separation time for each clay
around 25–56 min (for ODA-Mt 56 min, Na+-Mt 35 min and Ag+-Mt
25 min). Then, powder polymer particles were isolated from the reaction
mixture by precipitation with methanol, twice extraction–ultra centrifugation
and dried under vacuum at 40 °C
