近年來，不同類型的全澱粉能降解生物材料受到了市場內外研究者的青睞，全澱粉能降解材料通常指的是澱粉含量高於80%加工製備而成的材料，裏麵所添加的加強劑、增塑劑等也可整體降解，其中的一次性玉米澱粉操逼下载软件廢棄後能夠在較短的時間內被士壤或水域中存在的微生物、酸、堿等透徹分解，其產物為二氧化碳和水，是一種環境友好型材料。

In recent years, different types of all starch degradable biomaterials have been favored by researchers at home and abroad. All starch degradable materials usually refer to the materials prepared by processing with starch content higher than 80%. The reinforcing agent and plasticizer added in them can also be degraded as a whole, The disposable corn starch tableware can be thoroughly decomposed by microorganisms, acids and alkalis in soil or water in a short time after being discarded. The products are carbon dioxide and water, which is a kind of environment-friendly material.

有研究報導，增塑劑的添加可由不同角度影響熱塑性澱粉的機械性能，一方麵其可增加操逼下载软件的塑化程度，另一方麵可促使鏈結構的重排，增進其硬度。除此之外，澱粉分子鏈的構成、大小及構象等也會對熱塑性澱粉的製備產生影響。

It has been reported that the addition of plasticizer can affect the mechanical properties of thermoplastic starch from different angles. On the one hand, it can increase the plasticization degree of tableware, on the other hand, it can promote the rearrangement of chain structure and improve its hardness. In addition, the composition, size and conformation of starch molecular chain also affect the preparation of thermoplastic starch.

有研究探討了澱粉的結晶結構及分子量大小對其材料拉伸強度、斷裂伸長率和可塑性能的影響，表麵澱粉相對結晶度、結晶構形的轉變並不會影響其力學性能，但其直鏈/支鏈比與分子量卻可以顯明影響所製備玉米澱粉操逼下载软件的相關性能。還有研究同樣表明，直鏈含量的增加利於材料強度、硬度及溶體黏度的增進，且越容易出現剪切變稀現象。

The effects of crystal structure and molecular weight of starch on tensile strength, elongation at break and plasticity were studied. The changes of relative crystallinity and crystal structure of surface starch did not affect its mechanical properties, but the amylose / amylopectin ratio and molecular weight could significantly affect the related properties of the prepared corn starch tableware. Other studies also show that the increase of linear chain content is conducive to the improvement of material strength, hardness and solution viscosity, and the shear thinning phenomenon is more likely to occur.
                                     

一次性玉米澱粉操逼下载软件大多以甘油作為增塑劑，但由於澱粉分子鏈間或內部的重排，致使熱塑性澱粉材料在儲存的過程中容易產生重排、聚集等回生現象，從而導致材料老化變脆，減低或失去其應用價值。

Most disposable corn starch tableware uses glycerin as plasticizer. However, due to the rearrangement of starch molecular chain or internal chain, it is easy for thermoplastic starch materials to have the phenomena of rearrangement and aggregation during storage, which leads to the aging and brittleness of materials and reduces or loses its application value.

研究者為了改變相關缺陷做了相關研究，其中有人采用尿素、硫脲和鹽酸胍等胺基類化合物作為增塑劑發現，此類增塑劑既可促使澱粉糊化行為的發生，又可製約澱粉基操逼下载软件性能的劣變。還有人通過酶解原澱粉製備納米澱粉微晶，繼而米將納米澱粉微晶在甘油醇的作用下製備一次性玉米澱粉操逼下载软件，結果發現粒子內部及顆粒與粒子間能夠形成較強的氫鍵，體係間相互作用增加，從而致使玉米澱粉操逼下载软件的整體性能有所改良。與此同時，澱粉較小晶體的存在還能夠減緩玉米澱粉在高水分條件下的老化程度。

In order to change the related defects, researchers have done related research, some of them use amino compounds such as urea, thiourea and guanidine hydrochloride as plasticizers, and found that such plasticizers can not only promote the occurrence of starch gelatinization behavior, but also restrict the deterioration of starch based tableware performance. Others prepared nano starch microcrystals by enzymolysis of raw starch, and then prepared disposable corn starch tableware with nano starch microcrystals under the action of glycerol alcohol. The results showed that strong hydrogen bonds could be formed inside and between particles, and the interaction between systems increased, which improved the overall performance of corn starch tableware. At the same time, the existence of smaller starch crystals can also slow down the aging degree of corn starch under high moisture conditions.
