Thermosensitive ZrP-PNIPAM Pickering Emulsifier and the Controlled-Release Behavior
ACS Applied Materials & Interfaces, 2017 Asymmetric Janus and Gemini ZrP-PNIPAM monolayer nanoplates were obtained by exfoliation of two-dimensional layered ZrP disks whose surface was covalently modified with thermosensitive polymer PNIPAM.

Effects of stereochemistry and copolymerization on the LCST of PNIPAm
The Journal of Chemical Physics, 2017Poly(N-isopropylacrylamide) (PNIPAm) is a smart polymer that presents a lower critical transition temperature (LCST) of 305 K. Interestingly, this transition point falls within the range of the human body temperature, making PNIPAm a highly suitable candidate for bio-medical applications.

Langmuir, 2004
The adsorption of a rhodamine X labeled oligonucleotide composed of 25-mers of thymine (dT(25)-ROX) onto the thermosensitive shell of PMMA/PNIPAM core-shell latex particles was studied at 22 and 40 degrees C, below and above the T(VPT) (volume phase transition temperature) of the PNIPAM shell, respectively.

Synthesis and micelle behavior of (PNIPAm-PtBA-PNIPAm)m amphiphilic multiblock copolymer
Polymer, 2010Abstract A linear amphiphilic multiblock copolymer (PNIPAm-PtBA-PNIPAm)m was successfully synthesized by a two-step reversible addition–fragmentation transfer (RAFT) polymerization in the presence of a cyclic trithiocarbonate as RAFT agent. The micelle behavior of (PNIPAm-PtBA-PNIPAm)m multiblock copolymer in aqueous solution was then investigated by

Poly(N-Isopropylacrylamide) (PNIPAM) Is Never Hydrophobic
Journal of Colloid and Interface Science, 2010PNIPAM chains have hydrophobic and hydrophilic domains below and above the LCST. Temperature dependent interactions between PNIPAM and solutes arise because of changes in the local environment around the hydrophobic isopropyl domains. Below the LCST the isopropyl groups are surrounded by water, whereas above the LCST the hydrophobic groups are in ...

Preparation and Properties of Cyclodextrin/PNIPAm Microgels
Macromolecular Bioscience, 2009AbstractA two‐stage precipitation polymerization in aqueous solution was used to prepare β‐cyclodextrin/poly(N‐isopropylacrylamide) (β‐CD/PNIPAm) core–shell microgels. At the first stage, core microgels with CD moieties were synthesized by precipitation copolymerization of N‐isopropylacrylamide (NIPAm) with a monovinyl β‐CD monomer. At the second stage,
