Application

聚丙烯酸钠盐溶液已用于研究在Fe(lll)存在下，聚丙烯酸(PAA)超分子聚集体的形成机制。这种超分子作用捕获所有三价铁，抑制Fe(OH)3沉淀的形成。聚丙烯酸的螯合性可用于抑制氧化铁等铁氧化物的沉淀。

聚丙烯酸可用作正向渗透的驱动溶质，因其具有结构柔性和高水溶性。相比传统离子盐类更加优越，因其具有相当的水通量，但反向渗漏更少。

可用于研究PAA分子量对结晶中的CaCO3晶体成核与生长的影响。

Poly(acrylic acid) (PAA) coated-Fe3O4 superparamagnetic nano-composites were synthesized through a solvothermal technique by using cheap and environmental friendly iron salts and PAA. Each nano-composite was composed of many small primary nanocrystals. The as-synthesized products were characterized by X-ray diffraction (XRD)

Layer-by-Layer (LbL) Assembly, A "Gentle Yet Flexible" Method Toward Functional Biomaterials

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.
