摘要：

为提升光子晶体生色结构在纺织基材上的稳固性,以自交联型聚(苯乙烯-N-羟甲基丙烯酰胺)(P(St-NMA))胶体微球为结构基元,通过数码喷印技术将其施加到涤纶织物上构筑光子晶体生色结构。观测P(St-NMA)微球的形貌,表征光子晶体的排列和结构色效果,并测试和对比PSt和P(St-NMA)2种光子晶体生色结构在基材上的稳固性。结果表明:P(St-NMA)胶体微球具有典型的核壳结构,其中疏水性的聚苯乙烯(PSt)为核层,亲水性的聚N-羟甲基丙烯酰胺为壳层;P(St-NMA)光子晶体生色结构排列规整,色彩鲜艳、虹彩明显;相比PSt光子晶体生色结构,P(St-NMA)光子晶体生色结构的稳固性显著提升,经折叠、水洗后不易脱落。

Abstract:

In order to improve the stability of photonic crystals with structural colors on textile substrates, the poly(styrene-N-methylol acrylamide) (P(St-NMA)) colloidal microspheres with self-crosslinking were used as structural units to fabricate photonic crystals on polyester fabrics by a digital printing technology. The morphology of P(St-NMA) microspheres was observed, the arrangement and structural color effects of prepared photonic crystals were deeply characterized, and the stability of the P(St-NMA) photonic crystals with structural colors on the substrate was tested and compared with pure PSt photonic crystals. The results show that the P(St-NMA) colloidal microspheres present a typical core-shell structure, in which the hydrophobic PSt actes as the core layer and the hydrophilic PNMA as the shell layer. The prepared P(St-NMA) photonic crystals present regular arrangement, bright structural colors and obvious iridescence. Compared with pure PSt photonic crystals, the stability of P(St-NMA) photonic crystals is significantly improved, and P(St-NMA) photonic crystals are not easy to fall off the substrate surface after folding and washing. The improvement of the stability is attributed to the self-crosslinking between adjacent microspheres, which improves the bonding force between each other and enhances the bonding fastness between the photonic crystal layers and the substrates some extent.

Key words: self-crosslinking, P(St-NMA) colloidal microspheres, photonic crystal, structureal colors, polyester fabric
