A facile controlled-release nanogels delivery system has been developed by using hydroxypropyl methylcellulose (HPMC) hybrid nanogels as encapsulation shell materials, which were synthesized by surfactant-free polymerization in aqueous solution. The effects of reaction time and cross-linker concentration on the size of the nanogels have been studied. The results showed that in a certain range, the...
Surfactant-free hydroxypropylcellulose (HPC) nanogels were synthesized by using thermo-sensitive HPC as a template to form HPC/PMAA nanoscale complex. The formation mechanism was owing to the interpolymer hydrogen bonding between HPC and PMAA induced phase transition of HPC in aqueous media. The average size of the resulting HPC nanogels ranges from about 98 to 241nm. It was found that the average...
