With the development of technology and materials science, existing materials used to enhance the visual effects of martial arts performance costumes are difficult to achieve more futuristic and innovative visual effects, and cannot fully meet the needs of modern martial arts performance costume design. Therefore, this article aimed to study the application of π – conjugated materials to enhance the visual effect of martial arts performance costumes, enhance the artistic appeal and ornamental value of performances. At first, π-conjugated materials which are used for promoting the visual effect of martial arts performance clothes were chosen and devised. Secondly, according to the chosen π – conjugated material, the work of optical simulation and layout optimization was carried out. After that, the flow of making things was employed for structure optimization, hence to guarantee the best possible vision effects. In the end, the materials which are used for promoting the visual effect of martial arts performance clothes have been carried out comparison and analysis. The results showed that in terms of visual comfort and satisfaction, the use of π – conjugated material polystyrene had the highest score for martial arts performance costumes, which was 20.41% and 15.4% higher than the average score of costumes using the other two materials, respectively; on the aspect of color and tone matching, experts of martial arts performance clothing who also utilized π-conjugated material polystyrene gave the top score, which is 10.26% higher than the average score of clothing that uses the other two materials. With regard to the degree of gloss, the martial arts performance clothing that is made of π-conjugated material polystyrene presented an average gloss increment of 17.91% and 33.9%, respectively, when compared with the clothing made of the other two materials. On the aspect of the texture, the texture of martial arts performance costumes which use π – conjugated material polystyrene has more superior quality and is more appropriate for use. To make summation, the utilization of π-conjugated materials on martial arts performance clothing is advantageous for strengthening visual effects, and possesses high feasibility.
