- Thermally Induced Crosslinking of Poly(N-Propargyl Glycine)

Poly(N-propargyl glycine) undergoes crosslinking simply upon heating in the absence of any additives or metal catalysts. The crosslinking process is analyzed by thermal analysis (differential scanning calorimetry and thermogravimetric analysis), Fourier-transform infrared, electron paramagnetic resonance, and solid-state NMR spectroscopy.

Front Cover: Polymer carbon nanotube nanocomposites are prepared by melt-mixing a poly(oxymethylene)/poly(l-lactic acid) (POM/PLLA) blend and multiwalled carbon nanotubes (MWCNTs). Investigation of the crystallization behaviour shows that the MWCNTs first selectively nucleate POM to yield novel “mace-like” hybrid structure crystals, which then serve as efficient polymeric nucleating agents of PLLA. The crystallization rate and crystallinity are remarkably enhanced. Further details can be found in the article by Lijun Ye, Cuicui Ye, Xianchun Shi, Hengti Wang, Hongyan Zhao, Xiaojun Cao, Jichun You, Yongjin Li,* and Yuanyuan Liang on page 1801.
- Film Instability of Amphiphilic Block Copolymer Thin Films Driven by Solvent Annealing and Drying

In the early stages of solvent annealing, the merging of nanospheres to form nanocylinders gives rise to film rupture, creating holes of small size within a continuous layer. Upon further iterative solvent annealing and drying, flat islands progressively grow outward at the expense of expanding hole size until they contact with the edges of holes to form a network-like cellular structure, and then decay into hemispherical droplets.
